Support for FFI calls with `@Native external` functions through Native assets on Windows. This enables bundling native code without any build-system boilerplate code. For more info see: * https://github.com/flutter/flutter/issues/129757 ### 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`.
