  [flang][OpenMP] Implicitly map allocatable record fields (#117867)

This is a starting PR to implicitly map allocatable record fields.

This PR contains the following changes:
1. Re-purposes some of the utils used in `Lower/OpenMP.cpp` so that
   these utils work on the `mlir::Value` level rather than the
   `semantics::Symbol` level. This takes one step towards to enabling
   MLIR passes to more easily do some lowering themselves (e.g. creating
   `omp.map.bounds` ops for implicitely caputured data like this PR
   does).
2. Adds support for implicitely capturing and mapping allocatable fields
   in record types.

There is quite some distant to still cover to have full support for
this. I added a number of todos to guide further development.
