This patch includes a bunch of somewhat related fixes, these are:
- Ensuring that when a mochitest calls SimpleTest.expectChildProcessCrash()
the harness will wait for the crashes to be recorded before deleting the
dump files. This involves a message round-trip between the content and
parent process so to minimize its performance impact on all the non-crashing
tests it is done only when required.
- As an additional optimization, the SimpleTest harness will not send a
message to the content process anymore whenever it receives an
ipc:content-shutdown event, instead it does it only for abnormal shutdowns.
- Manually fixing remaining mochitests causing crashes to wait for crashes to
be recorded before finishing and deleting the dump files.
- Modifying BrowserTestUtils.crashBrowser() so that it optionally does not
delete the dump files, this is useful for tests that submit their dumps and
thus delete them on their own.

A simple solution to current timeouts. Several other tabcrashed tests
already use requestLongerTimeout -- it seems like these tests often have
a long run time.
* Toggle animate=false attribute on arrow panels when toolkit.cosmeticAnimations.enabled is false
* Use preferences-service component to lookup the pref in the arrowpanel binding
* Disable this pref during tests to remove a source of instability and timing-based test failures in chrome/UI tests.
* Enable cosmeticAnimations for tests which depend on existing behavior

There were options already being passed to BrowserTestUtils.removeTab, with only
a single property being observed, "dontRemove". This caused BrowserTestUtils.removeTab
to return a Promise once a tab is removed, but didn't actually remove the tab (as the
calling test would be responsible for that themselves). This patch removes that option,
and adds a method to BrowserTestUtils called tabRemoved to use for that case instead.
The options being passed to removeTab are now forwarded along directly to tabbrowser's
removeTab method.

As requested by UX. Disabling it behind a pref in case we decide we really
need to expose users to that form field again.
