radv: enable VK_EXT_separate_stencil_usage

This extension has been promoted to Vulkan 1.2 which means it has been
silently enabled when we implemented Vulkan 1.2.

Enable it explicitely to make mesamatrix happy and also for consistency.
This extension was designed for potential performance improvements of
MSAA depth/stencil images but it's currently a no-op in RADV.
