Add a11y titles for a few sysui windows

Adding for status bar, nav bar, and global actions dialog.
Also removing some extra code from global actions dialog
that populated window state changes. Apps in general don't
need this extra information, so we don't need to maintain
it in SysUi either.

In verifying the fix, I noticed that all windows were
considered anchored because of a mismatch between long and
int. Fixing that too.

Bug: 73131182
Test: With the testback a11y service, verified that these
titles do indeed appear in the window information provided
to accessibility services. Also noted that windows are no
longer reporting themselves as anchored.
