chore: cherry-pick ff0d013f60fa from chromium

[ppontes]

[86-LTS] Add AudioHandler to orphan handlers when context is suspended.

If the context is suspended, pulling of the audio graph is stopped.
But we still need to add the handler in this case so that when the
context is resumed, the handler is still alive until it can be safely
removed. Hence, we must still add the handler if the context is
suspended.

Test cases from issue 1176218 manually tested with no failures. Also
this doesn't cause any regressions in issue 1003807 and issue 1017961.
(Manually tested the test cases from those issues.)

(cherry picked from commit 4a38ea3f1f78e0a0ffc1464e227cee6c1f2fd90b)
