  [flang][OpenMP] Support custom mappers in target update to/from clauses (#169673)

Implement support for the OpenMP `mapper` modifier on `target update` `to` and
`from` clauses in Flang.

Semantic name resolution is extended to bind the mapper symbol for
`OmpClause::To` and `OmpClause::From` via a shared `ResolveMapperModifier`
helper. Lowering is extended in `ClauseProcessor` with a `getMapperIdentifier`
template helper to extract the mapper name for both `map` and `target update`
clauses and forward it to `omp.map_info`.

Fixes #168701.
