  -----------
  [lldb] Support overriding the disassembly CPU & features (#115382)

Add the ability to override the disassembly CPU and CPU features through
a target setting (`target.disassembly-cpu` and
`target.disassembly-features`) and a `disassemble` command option
(`--cpu` and `--features`).

This is especially relevant for architectures like RISC-V which relies
heavily on CPU extensions.

The majority of this patch is plumbing the options through. I recommend
looking at DisassemblerLLVMC and the test for the observable change in
behavior.
