  [MLIR][Math] Add fine-grained populate-patterns functions for math function rewrites. (#126103)

The existing `mlir::populateMathPolynomialApproximationPatterns` is
coarse-grained and inflexible:
- It populates 2 distinct classes of patterns: (1) polynomial
approximations, (2) expansions of operands to f32.
- It does not offer knobs to select which math functions to apply the
rewrites to.

This PR adds finer-grained populate-patterns functions, which take a
predicate lambda allowing the caller to control which math functions to
apply rewrites to.
