Tracker: Reimplement BSlowContextPopup as BPopUpNavMenu.

BSlowContextPopup was mostly a duplicate class of BNavMenu
only on top of BPopUpMenu instead of BMenu. Now, BPopUpNavMenu
just subclasses BNavMenu and adds the few features of BPopUpMenu
neccessary.

Drag-and-drop of files using the pop-up nav menu seems to still work fine.

Tracker: Style fixes to NavMenu.h

Pointer style, whitespace.

Convert TrackingHookData from a class to a struct (all members public)

Fix crash when dragging files onto nav menus.

- BNavMenu now keeps its own copy of the cached types list that's passed to it.
In some circumstances it could happen that the container window would
delete the list and consequently the nav menu would wind up with a pointer
to an invalid object. Probably a regression from the async mouse tracking
rewrites.

Overlooked this with my previous Trash-related changes: updated NavMenu to be
behaviorally in sync - it now hides the root volume Trash dir like PoseView,
and adds the Trash entry as needed when navigating down the Desktop.

* Rewrote BeBuild.h which had "a few" consequences (got rid of all those class
definitions).
* Minor cleanup here and there.
