  [DWARF] Add DW_MSPACE_LLVM_* memory space encodings (#220766)

DW_AT_LLVM_memory_space is already defined in Dwarf.def, and the memory
space encodings it takes are already specified in
docs/AMDGPUDwarfExtensionsForHeterogeneousDebugging.rst, but the values
had no names in the source, so llvm-dwarfdump printed the attribute as a
bare integer.

Add the encodings via a HANDLE_DW_MSPACE macro alongside the existing
HANDLE_DW_ASPACE, define the MemorySpace enum, and add MemorySpaceString
and getMemorySpace. AttributeValueString then resolves the attribute, so
no changes are needed in the DWARF consumers themselves.

Unlike address spaces, memory space encodings are target-independent, so
MemorySpaceString takes no triple.
