Relands "Changing `TextPainter.getOffsetForCaret` implementation to remove the logarithmic search (#143281)" (reverted in #143801) (#143954)

The original PR was reverted because the new caret positioning callpath triggered a skparagraph assert. The assert has been removed. Relanding the PR with no changes applied.

This pull request fixes #143803 by taking advantage of Dart's null-aware operators.

And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.

Part of https://github.com/flutter/flutter/issues/143616

Without this these tests only run on postsubmit which means we can't get gold results on PRs.

This was reverted because it landed after an engine change that broke flutter tester. That change has since been reverted.

Almost all of our devicelab devices are on iOS 17 now, so let's use them exclusively so we can verify that tests pass consistently on iOS 17.

Fixes https://github.com/flutter/flutter/issues/144020.

Attempting to fix https://github.com/flutter/flutter/issues/142125.

https://github.com/flutter/flutter/issues/143956

I still did not include a dartfix since a dartfix that replaces `release` with `dispose` would change the semantics and may cause a runtime crash instead of a build error.

@Piinks  does setting `bulkApply` to false force the user to apply the fix to every occurrence one by one in their IDE? If so then it seems that would be the way to go for this deprecation?

<blockquote>
<h1>CodeQL Action Changelog</h1>
<p>See the <a href="https://github.com/github/codeql-action/releases">releases page</a> for the relevant changes to the CodeQL CLI and language packs.</p>
<p>Note that the only difference between <code>v2</code> and <code>v3</code> of the CodeQL Action is the node version they support, with <code>v3</code> running on node 20 while we continue to release <code>v2</code> to support running on node 16. For example <code>3.22.11</code> was the first <code>v3</code> release and is functionally identical to <code>2.22.11</code>. This approach ensures an easy way to track exactly which features are included in different versions, indicated by the minor and patch version numbers.</p>
<h2>[UNRELEASED]</h2>
<p>No user facing changes.</p>
<h2>3.24.4 - 21 Feb 2024</h2>
<ul>
<li>Fix an issue where an existing, but empty, <code>/sys/fs/cgroup/cpuset.cpus</code> file always resulted in a single-threaded run. <a href="https://redirect.github.com/github/codeql-action/pull/2151">#2151</a></li>
<li>Update default CodeQL bundle version to 2.16.3. <a href="https://redirect.github.com/github/codeql-action/pull/2156">#2156</a></li>
</ul>
<h2>3.24.3 - 15 Feb 2024</h2>
<ul>
<li>Fix an issue where the CodeQL Action would fail to load a configuration specified by the <code>config</code> input to the <code>init</code> Action. <a href="https://redirect.github.com/github/codeql-action/pull/2147">#2147</a></li>
</ul>
<h2>3.24.2 - 15 Feb 2024</h2>
<ul>
<li>Enable improved multi-threaded performance on larger runners for GitHub Enterprise Server users. This feature is already available to GitHub.com users. <a href="https://redirect.github.com/github/codeql-action/pull/2141">#2141</a></li>
</ul>
<h2>3.24.1 - 13 Feb 2024</h2>
<ul>
<li>Update default CodeQL bundle version to 2.16.2. <a href="https://redirect.github.com/github/codeql-action/pull/2124">#2124</a></li>
<li>The CodeQL action no longer fails if it can't write to the telemetry api endpoint. <a href="https://redirect.github.com/github/codeql-action/pull/2121">#2121</a></li>
</ul>
<h2>3.24.0 - 02 Feb 2024</h2>
<ul>
<li>CodeQL Python analysis will no longer install dependencies on GitHub Enterprise Server, as is already the case for GitHub.com. See <a href="https://github.com/github/codeql-action/blob/main/#3230---08-jan-2024">release notes for 3.23.0</a> for more details. <a href="https://redirect.github.com/github/codeql-action/pull/2106">#2106</a></li>
</ul>
<h2>3.23.2 - 26 Jan 2024</h2>
<ul>
<li>On Linux, the maximum possible value for the <code>--threads</code> option now respects the CPU count as specified in <code>cgroup</code> files to more accurately reflect the number of available cores when running in containers. <a href="https://redirect.github.com/github/codeql-action/pull/2083">#2083</a></li>
<li>Update default CodeQL bundle version to 2.16.1. <a href="https://redirect.github.com/github/codeql-action/pull/2096">#2096</a></li>
</ul>
<h2>3.23.1 - 17 Jan 2024</h2>
<ul>
<li>Update default CodeQL bundle version to 2.16.0. <a href="https://redirect.github.com/github/codeql-action/pull/2073">#2073</a></li>
<li>Change the retention period for uploaded debug artifacts to 7 days. Previously, this was whatever the repository default was. <a href="https://redirect.github.com/github/codeql-action/pull/2079">#2079</a></li>
</ul>
<h2>3.23.0 - 08 Jan 2024</h2>
<ul>
<li>We are rolling out a feature in January 2024 that will disable Python dependency installation by default for all users. This improves the speed of analysis while having only a very minor impact on results. You can override this behavior by setting <code>CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION=false</code> in your workflow, however we plan to remove this ability in future versions of the CodeQL Action. <a href="https://redirect.github.com/github/codeql-action/pull/2031">#2031</a></li>
<li>The CodeQL Action now requires CodeQL version 2.11.6 or later. For more information, see <a href="https://github.com/github/codeql-action/blob/main/#2227---16-nov-2023">the corresponding changelog entry for CodeQL Action version 2.22.7</a>. <a href="https://redirect.github.com/github/codeql-action/pull/2009">#2009</a></li>
</ul>
<h2>3.22.12 - 22 Dec 2023</h2>
<ul>
<li>Update default CodeQL bundle version to 2.15.5. <a href="https://redirect.github.com/github/codeql-action/pull/2047">#2047</a></li>

Fixes an issue where if the `TextSpan` doesn't have a text style, the specified strutStyle is not applied.

Additionally, adds a migration flag for https://github.com/flutter/engine/pull/50385, for internal golden changes. It's only going to exist for a week.

### Description
- Adds `CurvedAnimation` disposals to `material/chip.dart`, `material/input_decorator.dart`, `material/toggleable.dart`, `widgets/animated_switcher.dart`, `widgets/overscroll_indicator.dart`.

Fixes a small documentation typo.

Fixed Small Typo in Emulators Test Name. I filed #140656 and it was fixed in #142853. I noticed this one there and decided to send a fix.

This PR implements the functionality described above and hides it behind
the `--experimental-faster-testing` flag of `flutter test`.

I don't know if this is feasible, but figured it was worth seeing.
Often times dart fixes are forgotten as part of the code review process.
I know some people ignore the PR template, but considered maybe a mention was warranted.

I've made the change reflected below:

My RenderSliverMultiBoxAdaptor/RenderSliverFixedExtentList/RenderSliverVariedExtentList yak shave continues.

I've been subclassing RenderSliverVariedExtentList for SliverTree and have found some opportunities for clean up.
There is a larger clean up I'd like to do, but this week SliverTree comes first. 

I noticed these methods were getting repeated 🔁, and I was about to repeat them again 🔁 for the tree, so I figured bumping them up to the base class was better than continuing to copy-paste the same methods.
