[Web Inspector] [Site Isolation] Add inspector test for
Page.overrideUserAgent with cross-origin iframes under site isolation
https://bugs.webkit.org/show_bug.cgi?id=310726
rdar://173344604
Reviewed by BJ Burg.
Add a layout test that verifies Page.overrideUserAgent propagates to
cross-origin iframes when site isolation is enabled. The test overrides the
user agent via Web Inspector, reloads, and confirms that navigator.userAgent
in a cross-origin iframe (running in a separate process) reflects the
overridden value.
The test crashes in Debug builds due to a pre-existing assertion in
JSC::Debugger::attach (ASSERTION FAILED: !globalObject->debugger()).
When the inspector connects to the cross-origin iframe's frame target
after a page reload, the debugger is already attached to the global object.
This is tracked as a known Debug crash in TestExpectations and will be
fixed in a follow-up.
