Native assets support for Windows (#134203)
Support for FFI calls with `@Native external` functions through Native assets on Windows. This enables bundling native code without any build-system boilerplate code.

### Implementation details for Windows.

Mainly follows the design of https://github.com/flutter/flutter/pull/134031.

Specifically for Windows in this PR is the logic for finding the compiler `cl.exe` and environment variables that contain the paths to the Windows headers `vcvars.bat` based on `vswhere.exe`.

Integration tests

These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Use this command to run (from the flutter_tools directory):

../../bin/cache/dart-sdk/bin/dart run test test/integration.shard

You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running ../../bin/flutter will automatically download it.

Coverage exclusion

These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.
