  [flang] Add hlfir.concat operation definition

This operation represents scalar character concatenation. This is
added as part of flang lowering update described in
https://github.com/llvm/llvm-project/blob/main/flang/docs/HighLevelFIR.md

A notable difference with Fortran concatenation is that hlfir.concat can
take two or more operands. This will be used to optimize concatenation
chains.
