Move DevToolsProtocolTest test harness to test support header

Preparation for  issue 874059  in which the DevToolsProtocolTest harness
is needed for verifying font selection, after discussion in
https://chromium-review.googlesource.com/c/chromium/src/+/1174540

Address banned and deprecated function warnings in the process: Using a
OnceClosure for closing the specific RunLoop to replace QuitCurrent()
and remove usage of RunMessageLoop(), mark NotificationMatcher as
RepeatingCallback.

Add a BrowserTest comparing matched fonts using DevTools protocol

For issue 828317 we need an end to test for checking whether the correct
fonts have been selected for @font-face { src: local(<fontname>) }
rules. Since this cannot be reliable verified with web platform API, I
am using DevTools to connect to the content instance and retrieve
information about the selected fonts, just like in the style panel of
DevTools. The DevTools protocol communication is modeled after
content/browser/devtools/protocol/devtools_protocol_browsertest.cc

I appreciate feedback on whether I should duplicate this DevTools
communication code here, whether there is an easier way to achieve this,
or whether we should factor out the relevant parts of
content/browser/devtools/protocol/devtools_protocol_browsertest.cc into
a separate file that I can reuse here for the FontUniqueNameBrowserTest.
