8b9e7602 - [RISCV] Don't use RVInstIBase for P-ext plui/pli. NFC (#149940)

[RISCV] Don't use RVInstIBase for P-ext plui/pli. NFC (#149940) These instructions don't have an rs1 field unlike other instructions that use RVInstIBase. Rename the classes to not use Unary since we have historically used that for a single register operand.
