target/riscv: Add zimop extension
Zimop extension defines an encoding space for 40 MOPs.The Zimop extension defines 32 MOP instructions named MOP.R.n, where n is an integer between 0 and 31, inclusive. The Zimop extension additionally defines 8 MOP instructions named MOP.RR.n, where n is an integer between 0 and 7.
These 40 MOPs initially are defined to simply write zero to x[rd], but are designed to be redefined by later extensions to perform some other action.
