ANGLE: Upgrade to version 1.2.30d6c255d238
The following patches have been changed:
0001-Fix-compilation-for-MSVC-2008-and-std-tuple.patch
Removed because it is no longer possible to build ANGLE with MSVC2008
0002-Fix-compilation-of-ANGLE-with-mingw-tdm64-gcc-4.8.1.patch
Removed because the minimum version of MinGW moved to 4.8.2
0005-Fix-build-when-SSE2-is-not-available.patch
Removed because it was fixed upstream
0006-Fix-compilation-of-libGLESv2-with-older-MinGW-w64-he.patch
Removed because older versions of MinGW are not supported
0007-Fix-ANGLE-build-with-Microsoft-Visual-Studio-14-CTP.patch
Removed because it was fixed upstream
Task-number: QTBUG-41903
