  [mlir] Add `arith-int-range-narrowing` pass (#112404)

This pass intended to narrow integer calculations to the specific
bitwidth, using `IntegerRangeAnalysis`.
We already have the `arith-int-narrowing` pass, but it mostly only doing
local analysis, while `IntegerRangeAnalysis` analyses entire program.
They ideally should be unified, but it's a task for the future.
