Don't show Inspector tabs that don't pertain to a selected object

[charlesh88]

Is your feature request related to a problem? Please describe.
Many sub-objects of views, when clicked, invoke Inspector tabs (like the Styles tab) that don't pertain to them, such as Time Strip swimlanes and their sub-objects.

Describe the solution you'd like
Selectable objects and sub-objects should have a method to disallow "standard" Inspector tabs that don't pertain to them.

This feature is required for #7936

Detailed matrix of desired tab visibility is here. High-level summary:

1. Only show Annotations tabs for views and sub-views that can be annotated, and don't show at all in edit mode.
2. Don't show Styles tab in browse mode. @jvigliotta says we can implement this in the Styles Inspector tab view provider.
3. Show the Elements pool in read-only mode in browse mode for those views that have it.
4. Generally, Properties is P1 in browse mode except for Plan Activities and Notebook Entries. In edit mode, Config is P1 for views that have it, followed by Elements and then Styles. Properties is always last priority in this mode.
