doc: Add doc for RISC-V Operand Modifiers
Document `z` and `i` operand modifiers, we have much more modifiers
other than those two, but they are the only two implement on both
GCC and LLVM, consider the compatibility I would like to document those
two first, and then review other modifiers later to see if any other should
expose and implement on RISC-V LLVM too.
gcc/ChangeLog:
* doc/extend.texi (RISC-V Operand Modifiers): New.
