Handle Clear* commands for layered framebuffers The patch adds support for clearing the layers of 2D array textures attached to a multi-view framebuffer. According to the ANGLE_multiview spec, the layers which are outside of the range [baseViewIndex; baseViewIndex + numViews) should remain unmodified. Because the native Clear* commands clear all of the layers, a workaround is implemented which creates a FBO, attaches a single layer from all multi-view attachments and clears the contents.
