Vulkan: Optimize full texture clears Currently, a full texture clear (glClearTexImageEXT()) is treated as a special case of a partial clear (glClearTexSubImageEXT() with image dims as the input). However, it can be further optimized by treating it as a clear update. * For full clears from EXT_clear_texture, the clear update path is taken. * It leads to a more optimized path, including the usage of the following APIs: * vkCmdClearColorImage() * vkCmdClearDepthStencilImage() * It uses the following enum: ClearTextureMode * If a partial clear uses the extents for the entire image, it is treated as a full clear. * Updated the method to determine if a texture is renderable in clearSubImageImpl(). * Added perf counter: fullImageClears * Added new unit tests * Single 3D texture full clear (Clear3DSingleFull) * 2D RGB SNORM clear (Clear2DRGB8Snorm) * Added Vulkan perf counter test for 2D and 3D color image clear. * Updated the related skipped tests on Pineapple.
