  [mlir] Fix UB in comparator lambdas in getRegisteredOperationsByDialect (#186428)

The comparators in `getRegisteredOperationsByDialect` and
`RegisteredOperationName::insert` were returning `StringRef::compare()`
directly (an `int`) instead of a boolean, breaking the strict weak
ordering requirement. Fix by using `StringRef` comparison operator `<`
directly.

Fixes #146940
