Send public types while showing or aborting transient bars

The sources with the same pulic type should be controlled together. So
we can just use public types to indicate which types of transient bars
are shown or aborted.

This CL also fixes bugs related to transient bars:
- Incorrect window layout after aborting transient bar. The transient
  state affects the window layout, but we didn't relayout after aborting
  it.
- Hiding taskbar won't trigger immersive mode confirmation. We only
  checked the visibility change of ITYPE_NAVIGATION_BAR before this CL,
  instead of all the sources with WindowInsets.Type#navigationbars().
- Transient taskbar won't show after performing the panic gesture. The
  reason is the same as the second bug above.
