Skip eglCreateContext telemetry for HWUI contexts

We want eglCreateContext telemetry to give us insights into how
developers use EGL. Including HWUI telemetry in this pollutes this
telemetry. Skip recording of the creation of this context using the new Egl extension. Currently this only disables the passing of GpuStatsInfo::Stats::CREATED_GLES_CONTEXT to the gpu stats.

Test: Checked the code path executed correctly with the flag enabled/disabled using logging
