Vulkan: Add missing EGLConfigs for Android Native pixel formats GL_RGBA16F correlates to HAL_PIXEL_FORMAT_RGBA_FP16. GL_RGB10_A2 that correlates to HAL_PIXEL_FORMAT_RGBA_1010102. This fills-in key holes between generated ANGLE config formats and the Android native formats after GL_RGB565 was added to fix the configs that were missing for some games. Modified EGLContextCompatibilityTest to exclude GL_RGB10_A2 and GL_RGBA16F from some of the EGLContextCompatibilityTest cases. EGLContextCompatibilityTest uses the OSWindow utility, which only works with UNORM-compatible EGLConfigs that are a proper subset of GL_RGBA8. The new configs won't work with the WindowDifferentConfig and WindowSameConfig test cases.
