fix: add persistable_bundle handling in codegen to restore full generation

The parcelable_gen.go codegen was missing persistable_bundle in four
switch cases: computeReachableWireFields, two unmarshal skip paths, and
the repeated-element marshal path. This caused the generator to silently
truncate reachable fields for any parcelable containing a
PersistableBundle, dropping ~900 Go files from the output (5169 instead
of 6079).
