[RISCV] Add ability to list extensions enabled for a target (#98207)
bb83a3d introduced `--print-enabled-extensions` command line option for
AArch64. This patch introduces RISC-V support for this option. This patch
adds documentation for this option.
`riscvExtensionsHelp` is renamed to `printSupportedExtensions` to by
synonymous with AArch64 and so it is clear what that function does.
