  -----------
  [TableGen] Add predicates for immediates comparison (#76004)

These predicates can be used to represent `<`, `<=`, `>`, `>=`.

And a predicate for `in range` is added.

  Log Message:
  -----------
  [RISCV] Use TableGen-based macro fusion (#72224)

We convert existed macro fusions to TableGen.

Bacause `Fusion` depend on `Instruction` definitions which is defined
below `RISCVFeatures.td`, so we recommend user to add fusion features
when defining new processor.
