EGL: Add wide-color tests

EGL: Add wide-color tests

Verify necessary extensions and functionality
is present to support wide-color. Specifically, pixel formats
FP16 and 10:10:10:2 and Display-P3 color space.

Test: adb -d shell \
      am start -n com.drawelements.deqp/android.app.NativeActivity \
      -e cmdLine '"deqp --deqp-case=dEQP-EGL.functional.wide_color.* \
      --deqp-log-filename=/sdcard/dEQP-Log.qpa"'

TODO:
- Do we need test for EGL_EXT_gl_colorspace_scrgb_linear?
  That should be no-op for driver.
