Reverts flutter/flutter#119495

We'll managed to optimize almost all of the cases that made this slow. Actually, it will soon be harder to optimize shader tiling...

Fixes https://github.com/flutter/flutter/issues/124703

Rather than applying an opacity layer per picker item, apply them to all partially opaque picker items at once. This dramatically improves performance for impeller, by reducing the number of required subpasses and texture allocations signficantly.

Before:
Doesn't finish, 100s of passes

Fixes #124756 by removing the concept of `Version.unknown`.

`Version` fields that needed the ability to represent an unknown version have been made nullable. Assigning `null` to them represents an unknown version.

This PR added optional labelText (which will be  rendered side by side with Checkbox in the future, and thus is also announced by default by screen readers), and semanticLabel(which will be announced by screen reader if provided, overrides labelText, in order to do that we might want to wrap the Text widget inside ExcludeSemantics in the future).

level formatting settings don't apply since they aren't as specific.
```
"[dart]": {

This PR handles this by turning off auto-formatting specifically for
Dart files.

This PR also adds `"files.trimTrailingWhitespace": true` to simplify

#123643
- Add task to projects evaluated by flutter.gradle that will print the
java version.
- Add integration test for the existence of javaVersion and the expected
format.
- Add gradle util to get the gradlew version for a specific platform
(gradlew everywhere but windows).

Why does this code need to exist? 
Figuring out what version of java is used by flutter/gradle is done in a
few different ways that are not always aligned.
See this issue https://github.com/flutter/flutter/issues/122609 ,
this issue https://github.com/flutter/flutter/issues/121501 this feature
request https://github.com/flutter/flutter/issues/106416

As examples of why assuming the java version is dangerous. 
This task is code flutter can build upon and is the version gradle is
using to build no matter how it is configured.
