pvr: Add VK_KHR_copy_commands2

We already expose the *2() functions and allow the common vulkan code
to provide the vulkan 1.0 equivalents, so we might as well expose this
extension.

Coverage in dEQP is dEQP-VK.api.copy_and_blit.copy_commands2.*, which
are mostly identical to dEQP-VK.api.copy_and_blit.core.* without
additional extensions.
