Refactor ResourceRequestAllowedNotifier EULA checking into a separate class.

This paves the way for making a EulaAcceptedNotifierAndroid class.

Also enables EULA logic tests on all platforms, not just ChromeOS
(since the EULA criteria are being mocked already).

No functionality changes.

BUG=226757
TEST=Existing unit tests.
