    Semantics no-op cleanups
   
    Partly in response to lmr's broad code review, I did a pass of
    superficial API/implementation cleanup.  The main changes are:
   
    - I changed each Boolean SemanticsProperty where false is equivalent to
      not being present to take "Unit" instead.  This is conceptually
      clearer: it avoids questions like "can I cancel out a semantics from a
      merged child by setting it to false?"  Because "property = Unit" looks
      weird, I also changed the style of these to "property()".
   
    - I moved the Semantics id generator closer to where it's used, in
      SemanticsModifierCore.  I made it internal and an AtomicInt.
      (Note that integer ids are heavily used in the Android
      AccessibilityNodeInfo APIs so I can't simply remove them entirely.)
   
    - I deleted dead code.  Some examples include SemanticsHintOverrides,
      a public API not connected to anything, and SemanticsPropertyKey
      merge() open method which is never called.  (In both cases I have
      a different plan in mind for accessibility.)
   
    Fixes: 145951226
    Fixes: 145955412
    Test: existing tests
    Relnote: "Single-value semantics properties now use a calling style.
    For example, 'semantics { hidden = true }' is now written as:
    'semantics { hidden() }'."

Yep, it appears that navigateUp() returns true, even when nothing visually changes on the screen. This seems to be caused by popBackStack(), which is always returning true even when popping the root Fragment.

    Fix popBackStack logic when popping the root destination
   
    popBackStack() and by extension navigateUp() should
    only return true if the user was successfully navigated
    to a new destination. In cases where the entire stack
    was popped, the methods should return false so that
    additional logic, such as finishing the activity, can
    be employed.
   
    This fixes a regression introduced in
