  [flang][OpenACC] Propagate acc.declare attribute to fir.global for USEd module variables (#192141)

When a module with `!$acc declare` is compiled separately from the
program that USEs it, `declareGlobal()` creates `fir.global` without the
`acc.declare` attribute. This causes implicit data mappings to override
device data that should already be present via `acc declare`.

The fix reads the symbol's `AccDeclare`/`AccCreate`/`AccCopyIn`/etc.
flags (already set from the `.mod` file by semantics) and attaches the
`acc.declare` attribute to the `fir.global`.
