Add setter to AcroFormField Subtype property

The Subtype property had only a getter which made it read-only. In JavaScript
non-strict mode, setting a getter-only property silently fails. But TypeScript
compiles to strict mode which throws an error.

Added a setter that stores the value in a private variable _Subtype. The getter
now checks if _Subtype was explicitly set and returns that, otherwise falls
back to the computed value (/Widget or null based on hasAnnotation).

This fixes the 6 failing acroform tests that were trying to set radioGroup.Subtype.
