Subject: [PATCH] refactor: move cgoSupported to internal/platform package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Created runtime/internal/lib/internal/platform package to house the
CgoSupported function, following the established pattern used by other
internal packages like internal/itoa.

Changes:
- Created runtime/internal/lib/internal/platform/platform.go
- Moved cgoSupported function to platform.CgoSupported
- Updated runtime/internal/lib/go/build/build.go to import and use
  the new package

This refactoring improves code organization by separating
platform-specific utilities into their own package, making the code
more maintainable and reusable.
