Loïc Sharma e54858b901 [Windows] Rename and move EGL types (flutter/engine#49900)
This is a refactoring with no semantic changes. The following types were renamed:

* `flutter::AngleSurfaceManager` to `flutter::egl::Manager`. In subsequent pull requests, this type will _create_ but not _own_ surfaces. Furthermore, this type will be split up to introduce `flutter::egl::Surface` and `flutter::egl::Context`. The manager will own the contexts and each surface will be owned by its view.
* `flutter::GlProcTable` to `flutter::egl::ProcTable`

This also introduces an `egl` directory to the Windows embedder.
