gdb: add risc-v disassembler options support

Browse Source 
This commit adds support for RISC-V disassembler options to GDB.  This
commit is based on this patch which was never committed:

  https://sourceware.org/pipermail/binutils/2021-January/114944.html

All of the binutils refactoring has been moved to a separate, earlier,
commit, so this commit is pretty straight forward, just registering
the required gdbarch hooks.
