[flutter_tools] move gradle helper methods into AndroidBuilder class body, split unit tests (#75931)

= gets escaped into %3D which seems to be tripping up cmake on windows since % is a control character. Switch to base64 encoding, since this does not have % nor , in the output character set.

This change is not trivially cherry pickable, and isn't tested on windows aside from my local, manual tests due to the planned CI work not being complete yet.

Fixes #75017
Fixes #74705

* opt out the flutter tool

* oops EOF

* fix import

* Update tool_backend.dart

* Update daemon_client.dart

* fix more

* Add text to --analyze-size command output to launch DevTools with size data.

Create symlinks for local engine Maven metadata files required by the Android Gradle plugin (#71600)

This reverts commit d688b52a.

This reverts commit 8e73bab9.

Remove devicelab specific code for shutting down gradle daemon, add --android-gradle-daemon option to build/run/drive`. Avoids need for un-tested devicelab specific handler. There are also some feature requests for this, so 2 birds one stone.

Example:

flutter build apk --no-android-gradle-daemon will pass --no-daemon on to gradle

HACKTOBERFEST

Teach the flutter tool how to find android output files if the flavor contains uppercase letters (#66687)

This changes the name of the generated output files on android in case a flavor with uppercase letters is used.
Previously, the lowercased flavor name would be used for the apk/aab file. Now, the flavor name is used as-is.

The flutter tool is currently unable to detect missing permissions in gradle/gradle.bat that would cause a gradle build to fail via process exception. Rather than crashing and exiting, we can display the exception as an error message and tool exit.

While linux/macOS are able to add the +x bit, this is not possible on windows with our current file system/OS API. These crashes represent a substantial amount of crash reporting, but are otherwise not actionable on our end.

* [flutter_tools] add analytics to code size, add more testing

* add gradle case

* Update build_macos_test.dart

* move analytics to code size tooling

* Update analyze_size.dart

* fix analysis

[flutter_tools] support code size tooling on iOS, linux, windows, macOS, and Android on Windows (#63610)

Adds support for size analysis on iOS, macOS, linux, and Windows - using an uncompressed directory based approach. The output format is not currently specified.

Adds support for size analysis on android on windows, switching to package:archive

Updates the console format to display as a tree, allowing longer paths. Increases the number of dart libraries shown (to avoid only ever printing the flutter/dart:ui libraries, which dominate the size)

* Add punctuation for unterminated sentences in doc comments

* Addressing review nit

Roll packages, update XML deprecations.
