riscv64: Codemotion cleanups to ISLE files (#5984)

Browse Source 
* riscv64: Fix typo in extensions

* riscv64: Move converters to top of file

* riscv64: Group up all imm12 rules

* riscv64: Move zero_reg helpers to Physical Regs section

* riscv64: Move helpers away from `clz` lowerings

These were in the middle of the `clz` rules and are kind of distracting

* riscv64: Move `cls` rules next to `ctz`/`clz`

* cranelift: Move `u8_and` / `u32_add` to Primitive Arithmetic section

* riscv64: Mark some imm12 constructors as pure

* cranelift: Move `s32_add_fallible` next to `u32_add`

* riscv64: Fix Typo
