[Mesa-dev] [PATCH] egl/android: Provide an option for the backend to expose KHR_image

[Harish Krupo]

>From android cts 8.0_r4, a new test case checks if all the required egl
extensions are exposed. In the current implementation we expose KHR_image
if KHR_image_base and KHR_image_pixmap are supported but KHR_image spec
does not mandate the existence of both the extensions.
This patch preserves the current check and also provides the backend
with an option to expose the KHR_image extension.

Test: run cts -m CtsOpenGLTestCases -t \
android.opengl.cts.OpenGlEsVersionTest#testRequiredEglExtensions
