1) To match the gyp dependencies, move clearkeycdmadapter binaries, plugins/,
   lib32/ and lib64/ from chrome.isolate to browser_tests.isolate.

2) On Windows, include <(version_full).manifest in chrome.isolate to be able
   to execute chrome.exe. Add needed chrome_child.dll and chrome_elf.dll.

3) Add libEGL.dll and libGLESv2.dll dependencies to gpu.gyp:gl_tests and a
   new angle.isolate; refer to it from gl_tests.isolate and
   gles2_conform_test.isolate.

4) Copy run_gpu_test to run_gpu_test.py, and invoke that instead in
   telemetry_gpu_test.isolate, to make this isolate work on Windows.
