[RISCV] Basic Objdump Mapping Symbol Support (#151452)
This implements very basic support for RISC-V mapping symbols in
llvm-objdump, sharing the implementation with how Arm/AArch64/CSKY
implement this feature.
This only supports the `$x` (instruction) and `$d` (data) mapping
symbols for RISC-V, and not the version of `$x` which includes an
architecture string suffix.
