0f8ad47b - [flang][acc] Accept component of global variable in `acc declare` (#197819)

[flang][acc] Accept component of global variable in `acc declare` (#197819) This MR partially extends the current implementation to accept cases of `acc declare` on a `parent%comp` whenever the `parent` has been `acc declare`d with the same clause. This is done by generating only the acc global constructor only for mapping the parent as the child is expected to be part of parent. The limitations still remain as a TODO unless it can be proven parent is mapped. A generic implementation would need either compiler generated ordering on the global constructors used for mapping or runtime managed ordering.
