Workaround for the case when task is letterboxed

There's a regression to make the task leash letterboxed in PIP animation
when enable_letterbox_translucent_activity is enabled even if the
activity matches parent.

This CL wordarounds to avoid overridding animation bounds if the task
is in size compat or letterboxed.

See b/376200414#comment6 to know how the transitions look like.
