  D3D11: Fix stale SRVs with tiny depth textures.
  
  When the tiny depth texture would get re-created on change, it was
  not freeing any cached SRVs which were pointing to the old tex.
  Fix this by erasing the cache entry if the texure is recreated.
  
  Also include a test which hooks into the workarounds to force
  testing on every platform.
  
  Also narrow the workaround to only apply to depth/stencil textures
  which use these mips in GL, rather than D3D, where we always create
  a full mip chain.
