[Mlir-commits] [mlir] [mlir] Use bind_front in RemarkEngine. NFC. (PR #175818)

[Jakub Kuderski]

https://github.com/kuhar created https://github.com/llvm/llvm-project/pull/175818

Switch from C++11 `std::bind` to C++26 `bind_front` backported in https://github.com/llvm/llvm-project/pull/175056.

The former is an old design that predates lambdas and uses explicit placeholders. `bind_front` should produce a much smaller object (we only need one pointer).
