Split from #66776

Even if pub does not change the packge_config contents, it will still update a timestamp in one of the fields. This causes unnecessary rebuilds. To fix this, generate an additional file when running pub get that only contains the relevant fields and then update the KernelSnapshot rule to depend on it only.

If a file scheme and one or more roots is provided, fall back to this mapping before the direct file path if the file path cannot be turned into a package URI.

Use URI representation so that the transformation is resilient to the org-dartlang-app scheme used by the web builds.

[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)

Remove globals and testbed to simplify test cases, using the existing environment configuration. This is some pre-factoring work to make landing #63610 easier

Revert "[flutter_tools] separate target platform, host platform, and architecutre (#60119)" (#60147)

This reverts commit 30d97d89.

separate target platform, host platform, and architecture

Instead of targets/dart.dart -> targets/common.dart

* Revert "[flutter_tools] Put a heap size limit on the frontend_server (#58039)"

Builds and bundles an 'app.so' containing AOT data, and downloads and packages the release/profile artifacts for those builds, rather than always using the debug artifacts.
