This will set the color buffer load_op to DONT_CARE if the application
has invalidated the color buffers prior to drawing.
Will also set load_op to DONT_CARE for depth & stencil, though this
isn't likely a common use case.
Tests:
angle_deqp_gles3_tests --gtest_filter=dEQP.GLES3/functional_fbo_invalidate_* --use-angle=vulkan
angle_end2end_tests --use-angle=vulkan --gtest_filter=StateChangeRenderTestES3.InvalidateNonCurrentFramebuffer/ES3_Vulkan
