Add environment variable to switch between metal and opengl
Not yet tested, don't know how to build angle on macOS (could the github build workflow be run?)

@GameParrot there is already such a switch, needs a angle build with metal enabled (see 0.6.0 dmg file).

  • force opengl ANGLE_DEFAULT_PLATFORM=gl
  • use metal ANGLE_DEFAULT_PLATFORM=metal
    • my changes are
      • a fallback to opengl to not fail egl init
      • prefer metal over opengl

This CL improves performance compared to the existing code as well as
allows using non-std mutex implementations. Also acts as a base for
future changes.

CL adds new build option:
    angle_enable_global_mutex_recursion = is_android && angle_enable_vulkan

"mutex_recursion" work same way as `std::recursive_mutex` before. It
will help in situations when Vulkan API may return back to the ANGLE.
For example: RenderDoc layer EGL deadlock.
Automatic loading of "libVkLayer_GLES_RenderDoc.so" layer causes
deadlock in EGL.

    google#26 pc 000000000029c7e8  /vendor/lib64/egl/libGLESv2_angle.so (EGL_Initialize+192)

Additionally, recursive mutex will partially solve Android
SurfaceTexture deadlock (angleproject:4354).

Some performance numbers for 1000'000 `eglGetError()` calls.

Happens only on platforms that use "EGL_KHR_fence_sync" instead of
"EGL_ANDROID_native_fence_sync" for synchronization. Happens only on
specific Surface types, that using `EGLConsumer`/`GLConsumer`, such as
`SurfaceTexture`.

The Android's "testDrawingHardwareBitmapNotLeaking" test may be used for
testing the issue. Note: in order to reproduce, `SingleContextMutex`
must not be used by context. The "Fix ExternalImageTarget EGLImage race"
CL will achieve that.

To check what extension is used, call:
    adb shell "dumpsys SurfaceFlinger | grep 'Sync configuration'"
Possible results:
    Sync configuration: [using: EGL_KHR_fence_sync EGL_KHR_wait_sync]
    Sync configuration: [using: EGL_ANDROID_native_fence_sync EGL_KHR_wait_sync]
