[Parcel] Expand types from TypeParceler annotation to support aliases

Class properties are being expanded before checking for custom
parcelers, which makes custom parcelers of type alias unable to be
found. To maintain K1 behavior, the custom parceler type must also be
expanded, so even the aliased type is supported when used in its raw
form as a class property.
