ANGLE: Update to version 2446
Update ANGLE and reapply patches.
Patch changes:
"Dynamically resolve functions of dwmapi.dll"
Removed; ANGLE no longer uses DWM API
"Make it possible to link ANGLE statically for single-thread use"
Avoid name collision by using ANGLE-style getCurrent()
"Fix build when SSE2 is not available."
Added guard for __cpuid(), which is not available on ARM
"Make DX9/DX11 mutually exclusive"
Adjustments due to underlying code changes
"ANGLE: Avoid memory copies on buffers when data is null"
Removed; fixed upstream
"Add missing intrin.h include for __cpuid"
Removed; fixed upstream
