TopSupported and SkipSupported non-nullable with DefaultValue="true"

[HeikoTheissen]

Fixes #322

Assume an entity set of singleton $S$ with a non-containment navigation property $p$ and a navigation property binding of $S/p$ to the entity set or singleton $T$.

If $S$ is annotated with Capabilities.NavigationRestrictions/RestrictedProperties annotation with NavigationProperty${}=p$ but without TopSupported, the default value TopSupported=true is implied and hence the resource path $S/p$ supports $top, regardless of any annotation Capabilities.TopSupported on $T$. Analogous for SkipSupported.

The V4-CSDL-to-OpenAPI.xsl tool currently behaves differently: In the absence of Capabilities.NavigationRestrictions/RestrictedProperties/TopSupported on $S$ it evaluates Capabilities.TopSupported on $T$, ignoring the default value.

This PR corrects the behavior of the tool. The correction results in additional parameters

{"$ref": "#/parameters/top"},
{"$ref": "#/parameters/skip"}

in some of the examples.

@HeikoTheissen Do you want to make the same change to the JavaScript version of the tool?

One more thing: please bump the package version via command

npm version minor

and add an entry to the changelog.
