RISC-V: rename parse_asm.h to insn.h

The current parse_asm header should become a more centralized place
for everything concerning parsing and constructing instructions.

We already have a header insn-def.h similar to aarch64, so rename
parse_asm.h to insn.h (again similar to aarch64) to show that it's
meant for more than simple instruction parsing.
