widl: Consolidate top-level parameter conformance/variance expression writing into a separate function.

Descend through as many pointer types as necessary to find the
fundamental type and determine whether it needs a top-level parameter
conformance/variance expression to be written.

Add support for writing top-level parameter conformance/variance
expressions for non-encapsulated unions.
