Add microbenchmarks for vkCmdClear*Image

vkCmdClearColorImage() and vkCmdClearDepthStencilImage() are currently
implemented using Blitter::clear(), which delegates to fastClear() for
certain formats, or falls back to using a generic Reactor routine.

This change benchmarks the performance for:
 - VK_FORMAT_R8G8B8A8_UNORM (fast path)
 - VK_FORMAT_R32_SFLOAT (slow path)
 - VK_FORMAT_D32_SFLOAT (slow path)
