vulkan: add common VK_PRINT_STR/VK_COPY_STR macros

every vk driver wants these macros for executable statistics, so make them
common. there are two variants floating in-tree, a pure copy (radv) and a
formatted print (everyone else). we add both variants and then convert most
prints to copies where formatting isn't actually used. that has the benefit of
cleaning up trivial "%s" format strings in a bunch of places.

I didn't bother cleaning up the formatting in non-automatic-formatted drivers
because it's tedious and I'm planning to delete a lot of this driver code with
upcoming runtime work anyway. This is a step towards those runtime improvements.
