Store and retrieve the view type, per object type

[charlesh88]

Closes #1395

Describe your changes:

• TLDR: the view switcher now locally stores and restores the last selected view for a given object type. This makes a folder's List View actually usable as the view persists as you navigate folders, rather than completely useless as in the current behavior of constantly reverting to the grid view.
• Interacting with the view switcher in any view that uses it now stores that selection as a "view preference" for that object type in a localstorage object named 'openmct-stored-view-prefs'.
• Browse.js > #navigateToPath now retrieves the stored view preference when its currentViewKey argument is undefined. This allows bookmarked views or links that include a view searchparam to force a particular view when desired. Navving to a link in this way doesn't update the stored preference; that only occurs when the view switcher is actively changed by the user.
