anv: bump internal descriptor index fields to 32bits

Prior to supporting VK_EXT_descriptor_indexing all of our descriptor
limits where below 64k which fitted a uint16_t. Now all of those can
go up to 2^20 entries so we need 32bits indexes to keep track of them.

This change leaves the dynamic indexes at 16bits. We could arguably
bump them too, up to the reviewer's taste.
