turnip: Drop the copy of the formats table.

turnip: Drop the copy of the formats table.

Now that we can (mostly) generate a pipe format for a VkFormat, use that
to answer queries about formats.  This will let us refactor the freedreno
format table surface layout code to be shared between gallium and vulkan.

This causes us to expose fewer formats for now (on a 1/100 CTS run I'm
doing, skips go from 3671 to 3835 out of 5145 tests).  Fails stay about
the same (478 -> 434, but the run is pretty flaky and we're doing fewer
tests now).

v2: Rebase on master, throw a finishme on missing vk-to-pipe formats that
    tu used to support.
