Default theme: Tag-based visibilityFilter supports signatures

[XeroAlpha]

Changes

1. Introduces the capability to apply visibility filters based on (modifier) tags at the method signature, accessor signature, and index signature levels.

2. If visibility of every signature is affected by the same tag, this influence is now elevated to the method or accessor itself. This change ensures that when all signatures of a method/accessor are filtered out (hidden), the method/accessor title will also be hidden accordingly. This modification addresses the issue where method/accessor titles were still visible even though all their signatures were hidden.

3. Previously, the visibility of index signature container element was determined by whether the class they belonged to met the filter criteria. This behavior has been altered so that these container elements are no longer influenced by the filter settings.

Known Issues

• Index signatures do not support "Inherited" and "External" filters. This limitation arises because the parent DeclarationReflection of an index signature SignatureReflection is the class it belongs to, instead of any method or property DeclarationReflection. Class DeclarationReflection is not Inheritable, since it cannot be a member of class/interface.
