spirv,radv,anv: implement no-op VK_GOOGLE_user_type

This extension only allows HLSL shader compilers to optionally embed
unambiguous type information which can be safely ignored by the driver.

This fixes a crash with the recent Vulkan backend of Path Of Exile
(it uses the extension without checking if it's supported).
