Allow Softlock to happen in most contexts

All this tested on erosq, I'm not sure if this will break on other targets or if there is a reason this shouldn't be done.

apps/menu.c:

Added CONTEXT_MAINMENU|ALLOW_SOFTLOCK in do_menu(), this allows the user to lock the keys in most places within the main menu tree.

apps/tree.c:

Added CONTEXT_TREE|ALLOW_SOFTLOCK in dirbrowse(), this allows locking the keys in most other contexts not covered by the above.

Notable exceptions I've found that still cannot be locked: View Playlist, any settings change screen (ex. Shuffle No/Yes, Volume Select dB)

Adding fix for Advanced Key Lock feature brought to light by this change in apps/action.c.

Expected behavior for Advanced keylock is now (according to my testing here):
        Volume:	Can be exempted	from keylock anywhere
        Skip/Scrollwheel: Can only be exempted in WPS
        Seek: Can only be exempted in WPS
        Play: Can only be exempted in WPS

Backlight exemption is same except the Volume exemption doesn't work outside the WPS, but I don't believe that is due to this change.
