Move //third_party/glfw to //flutter/third_party/glfw

As part of eliminating the Flutter buildroot (#67373), we are moving all
third-party dependencies from //third_party to //flutter/third_party.

This is the engine-side follow-up to flutter/buildroot#777.

Once all third-party dependencies have been migrated, tooling and config
will be moved and the buildroot will be eliminated altogether.

Issue: flutter/flutter#136284
