Activate wildcard imports for bare delay identifiers

Bare identifiers used as unparenthesized delays construct `PEIdent` directly.
This bypasses wildcard package import activation, so a delay reference after
an import can resolve to an outer declaration instead of the imported name.

Create the identifier through `pform_new_ident()` so the import becomes
visible at the reference's lexical position.
