[GLESv3] Add KHR_create_context semantics

If the ES 3.x feature is enabled:

1. If not on GLES1, select the highest available 3.x context if
   major version was not specified.
2. If on GLES2, upgrade to highest available 3.x context.

- In this case, need to allow GL_HALF_FLOAT_OES through to
keep from regressing CTS dEQP-GLES2.functional.fbo.completeness
if the feature is enabled.
