Upgrade ANGLE to 1.3.5bb7ec572d0a

This brings Qt's copy of ANGLE up to ANGLE master, which contains a number
of bugfixes as well as restructuring for the upcoming ES 3.0 support. This
version brings considerable stability improvements to the D3D11 renderer.

The static translator project files have been merged to align with the
ANGLE source tree.

Two new patches have been applied to fix errors in upstream ANGLE:
- 0011-ANGLE-Fix-compilation-error-on-MinGW-caused-by-trace.patch
  The event trace header in ANGLE's third_party directory has an unused
  template which causes a compilation error on MinGW. Disable this part
  of the code.
- 0012-ANGLE-fix-semantic-index-lookup.patch
  The sorted semantic index table was returning a direct mapping to the
  new indices, instead of the old indices. This caused a mismatch in the
  GL type lookup for the translated attribute.

All other patches have been rebased, removed if no longer needed,
and renamed to clear up the application order:
- 0001-Fix-compilation-for-MSVC-2008-and-std-tuple.patch
  No changes.
- 0001-Fix-compilation-with-MinGW-mingw-tdm64-gcc-4.8.1.patch
  No changes. Renamed to 0002.
- 0001-Fix-compilation-with-MinGW-gcc-64-bit.patch
  No changes. Renamed to 0003.
- 0001-Make-it-possible-to-link-ANGLE-statically-for-single.patch
  Modified patch to adapt to new DLL loading structure. Renamed to 0004.
- 0005-Fix-build-when-SSE2-is-not-available.patch
  No changes.
- 0011-Fix-compilation-of-libGLESv2-with-older-MinGW-w64-he.patch
  No changes. Renamed to 0006.
- 0006-Make-DX9-DX11-mutually-exclusive.patch
  Made the patch less invasive by allowing D3D9 code to run unless
  explicitly disabled (e.g. on WinRT, where it doesn't compile). This
  makes the patch smaller and allows Desktop Windows to compile both
  D3D9 and D3D11 codepaths. Renamed to 0007.
- 0015-ANGLE-Dynamically-load-D3D-compiler-from-a-list-of-k.patch
  No changes. Renamed to 0008.
- 0012-ANGLE-Support-WinRT.patch
  Made D3D11_level9 initialization only possible if D3D9 is disabled.
  This makes sure Desktop PCs use the old D3D9 codepath instead of
  the less-tested D3D11_level9 codepath. Renamed to 0009.
- 0013-Enable-D3D11-for-feature-level-9-cards.patch
  Conveniently smaller patch due to buffer implementation improvements
  upstream. Renamed to 0010.
- 0014-ANGLE-D3D11-Alwayls-execute-QueryInterface.patch
  This was a fix for patch 0009, so was integrated there. Removed.
- 0016-ANGLE-D3D11-Fix-build-on-desktop-Windows.patch
  This was a fix for patch 0009, so it was integrated there. Removed.
- 0001-ANGLE-Fix-compilation-with-MSVC2013.patch
  Fixed upstream. Removed.
- 0007-ANGLE-Fix-typedefs-for-Win64.patch
  Fixed upstream. Removed.
- 0004-Fix-black-screen-after-minimizing-OpenGL-window-with.patch
  The issue has been fixed in Qt itself. Removed.
- 0008-DX11-Prevent-assert-when-view-is-minimized-or-.patch
  The cause of the problem was the same as patch 0004, but for the
  D3D11 codepath. Removed.
