  [DWARFYAML] Implement debug_names support (#79666)

This commit brings support for debug_names in DWARFYAML. It parses YAML
and generates emits a DWARF5 Accelerator table with the following
limitations:

1. All forms must have a fixed length (zero length is also ok).
2. Hard-coded support for DWARF 5 and DWARF32.
3. The generated table does not contain a hash index

All of these limitations can be lifted in the future, but for now this
is good enough to enable testing.
