Vulkan: Move texture QFOTs to syncState() ... (and getAttachmentRenderTarget() which is syncState()-like for deferred clear) so that QFOTs are not actually scheduled until first use. SurfaceFlinger optimistically creates EGL images and textures for AHBs in case it does need them in the future. However, the images and textures may go unused. Prior to this change, ANGLE would create pending QFOT barriers while importing AHBs into EGL images and GL textures. However, SurfaceFlinger may not be doing any "real work" (other than repeatedly creating and destroying EGL images and GL textures) which would result in the command buffers containing the QFOTs being flushed. This can result in a large build up of unreleased memory (as the VkDeviceMemory would still be kept alive by the reference from the unflushed QFOT command buffer) and lead to the low memory killer nuking processes.
