Auto merge of #22234 - jdm:android-gl-crash, r=Manishearth

Fix android GL crash

There were two issues, fundamentally:
1. POINT_SPRITE is not supported on GLES, which was causing the GL_INVALID_ENUM error when using any WebGL API.
2. The version check was using the wrong version value to determine if enabling point sprites was necessary.
