Enable the OpenGLES backend on Android.
Please include the following text as part of the Dawn->Chromium roll, as well as the footer "Binary-Size: See commit description":
This CL enables the Dawn GLES backend in Chrome on Android. This increases the APK size by ~143K. This functionality is necessary to increase the reach of WebGPU in Chrome to include Android devices without Vulkan support. It will also allow the use of Dawn's GLES backend for Skia/Graphite on Android, allowing a future binary size reduction when the ANGLE native backends are removed from the GPU process.
Previous work reduced the binary size increase from 182K -> 153K:

And from 153K -> 143K:
