  [flang][OpenMP] Translate OpenMP scopes when compiling for target device (#130078)

If a `target` directive is nested in a host OpenMP directive (e.g.
parallel, task, or a worksharing loop), flang currently crashes if the
target directive-related MLIR ops (e.g. `omp.map.bounds` and
`omp.map.info` depends on SSA values defined inside the parent host
OpenMP directives/ops.

This PR tries to solve this problem by treating these parent OpenMP ops
as "SSA scopes". Whenever we are translating for the device, instead of
completely translating host ops, we just tranlate their MLIR ops as pure
SSA values.
