riscv: add kernel command line option to opt out of user CFI
Add a kernel command line option to disable part or all
of user CFI. User backward CFI and forward CFI can be controlled
independently. The kernel command line parameter "riscv_nousercfi" can
take the following values:
- "all" : Disable forward and backward cfi both
- "bcfi" : Disable backward cfi
- "fcfi" : Disable forward cfi
