radv: Support VK_EXT_inline_uniform_block.
Basically just reserve the memory in the descriptor sets.
On the shader side we construct a buffer descriptor, since
AFAIU VGPR indexing on 32-bit pointers in LLVM is still broken.
This fully supports update after bind and variable descriptor set
sizes. However, the limits are somewhat arbitrary and are mostly
about finding a reasonable division of a 2 GiB max memory size over
the set.
v2: - rebased on top of master (Samuel)
- remove the loading resources rework (Samuel)
- only load UBO descriptors if it's a pointer (Samuel)
- use LLVMBuildPtrToInt to avoid IR failures (Samuel)
