fix: disable nodeIntegration & insecure resource warnings for localhost (#18814)

Browse source 
* fix: disable remote host nodeIntegration warning for localhost

In warnAboutNodeWithRemoteContent(), add a check to see if the hostname
is "localhost" and prevent the warning message if it is.

* fix: disable loading insecure resources warning for localhost

In warnAboutInsecureResources(), filter out resources from localhost
since they are most likely not a threat.

* test: add tests for ignoring security warnings when using localhost

Add tests for ignoring warning messages for the following scenarios:
  1. node integration with remote content from localhost
  2. loading insecure resources from localhost

* test: fix insecure resource test

* test: pass nodeIntegration with remote test on did-finish-load

* test: maybe fix node integration test (error w/ conv circular struct)

* test: update test description

* test: use "load" event to check when nodeIntegration test has finished

Instead of relying on the "did-finish-load" event, which may result in
a race condition, add an "onload" handler that logs "loaded" to the
console. This will execute _after_ the nodeIntegration check, so it
can be safely used as a signal to indicate that the test is done.

* test: rename base-page-security-load-message.html

* fix: ignore enabled remote module warning for localhost

* refactor: add isLocalhost()
