  -----------
  [MLIR][LLVM] Add ftz and fuse FP ops related function attribute support (#97812)

Adds `denormal-fp-math-f32`, `denormal-fp-math`, `fp-contract` to
llvmFuncOp attributes.

`denormal-fp-math-f32` and `denormal-fp-math` can enable the ftz, that
is , flushing denormal to zero.

`fp-contract` can enable the fma fusion such as `mul + add -> fma`
