Upgrade to address issues discovered since the last upgrade.

Patch notes:
0000-General-fixes-for-ANGLE-2.1.patch
  added removal of the unused third-party tracing functions

0003-Fix-compilation-with-MinGW-gcc-64-bit.patch
  removed as it is no longer needed

0011-ANGLE-Fix-compilation-error-on-MinGW-caused-by-trace.patch
  removed as it is no longer needed

0016-ANGLE-Fix-compilation-with-MinGW-D3D11.patch
  now supports MinGW 64-bit
