Rename the tests in webrtc/legacy to have optional flags

These tests are, if I'm not mistaken, entirely testing behaviour in
https://w3c.github.io/webrtc-pc/#legacy-interface-extensions, which
opens with:

Supporting the methods in this section is optional. However, if
these methods are supported it is mandatory to implement according
to what is specified here.

Thus the behaviours tested within these tests are not mandatory tests,
and thus they must be marked as optional. (Arguably, they could be
made to be mandatory tests, if they simply allow for the overload not
being supported, but that's much harder to achieve.)

webnn: implement quantizeLinear on coreml

Implement quantizeLinear using CoreML quantize op.

Add a cast_to_supported_type flag to webnn_conformance_test that skips
return early when input/output doesn't match opSupportLimits.
buildAndExecuteGraphFunc already has logic that handles implicit
casting.

Consolidate reference_file and is_test_reference into a single param

The Canvas WPT test generator was using two variables to control how a
test file links to it's reference file: 'reference_file' and
'is_test_reference'. In the context of documenting all parameters,
having to explain why we have two different parameters to do this one
thing is awkward. The logic and documentation will be simpler by using a
single 'reference_file_link' parameter.

Handle overlay scrollbars gracefully in auto-scrollbars.html

The WPT test auto-scrollbars.html depends on the browser not having
overlay scrollbars. This test has been consistently failing on mac due
to failing this assertion:
https://luci-milo.appspot.com/ui/tests/p/chromium/rules/751e05390273c6cfc8bf07cc5d245522?annotated=false&historyTimeRange=30d&selectedMetrics=human-cls-failed-presubmit%2Ccritical-failures-exonerated%2Cfailures%2Cbuilds-failed-due-to-flaky-tests&tab=recent-failures&groupBy=os

This CL changes the file so that tests are skipped when overlay
scrollbars are detected instead of crashing after failing the
assertion.

Crbug 398159676 was created as a follow up of this CL to make our
infra handle assert_implements_optional as not failures. After that
work is completed, this CL will be reverted and the assert will be
restored.

DOM: Implement finally() Observable operator

See WICG/observable#153. This CL implements the
finally() operator. It registers a callback which runs on both
producer-initiated and consumer-initiated unsubscription. Its
implementation is relatively straightforward, just utilizing the
relevant subscriber's teardown list.

This CL used to be really complicated, as was the spec PR. This has all
been simplified since the factors that made it complicated (and broken)
have been landed. See:

• WICG/observable#151 (comment)
• WICG/observable#154
• https://crrev.com/c/5676226

Now that the simplifying factors have been landed, this CL can proceed
with a simple implementation, which passes all of the tests.

Add larger outline for elements with interesttarget

Per the explainer:

https://open-ui.org/components/interest-invokers.explainer/#keyboard

It is desirable to have a way for users to "know" that an element
has the interesttarget attribute, and therefore that there are additional actions they can take to invoke it.
