Switch Java calls to enableZ and disableZ; remove isRecordingFor

Bug: 155422223
Test: make

insertInOrderBarrier and insertReorderBarrier are @hide and deprecated.
Remove them and update all callers to enableZ and disableZ, which are
already public.

Update native code to refer to enableZ instead of insertReorderBarrier.

In addition, remove @hide Canvas#isRecordingFor. This method was
originally used to prevent a single RenderNode from being in two display
lists. This is now supported, so there's no reason to avoid it. The one
caller used it to determine whether to reorder drawing its child Views
(which, as the comment says, makes sense to determine based on whether
the Canvas isHardwareAccelerated) and whether to call
insertReorderBarrier/insertInOrderBarrier (now enableZ/disableZ). In the
latter case, there is no need for a conditional, since enableZ/disableZ
only work on a hardware Canvas.
