  CL: OpenCL support for ANGLE Capture/Replay
  
  Implementation of OpenCL Capture/Replay tool in ANGLE.
  Brief notes about the change:
  - Most meaningful changes for the capture process are
    made in src/libANGLE/capture/
  - Most meaningful changes for replay are made in
    util/capture/ and src/tests/perf_tests/
  - Many autogenerated files are changed/added to allow
    the capture of OpenCL objects & calls
  - The following applications were captured/replayed:
    benchmark_model, GeekBench Compute, GeekBench ML,
    AI-Benchmark, various OCL CTS tests
  - End2end test added to capture_tests.
    CapturedTestCL.MultiFrameCL/ES3_Vulkan
