RISC-V: Handle implied extension in multilib-generator

 - -march has handle implied extension for a while, so I think
   multilib-generator should handle this well too.

 - Currently only add rule for D imply F.

gcc/ChangeLog:

* config/riscv/multilib-generator (IMPLIED_EXT): New.
(arch_canonicalize): Update comment and handle implied extensions.
