Introduces JUnitTestGURLs, which returns GURLs generated from serialized
GURLs for use in junit tests where the native library cannot be loaded.

This allows junit tests to do simple operations with GURLs and allow
unit testing of classes that use GURL without caring too much about more
complex things like formatting or comparing origins, etc.

The alternative to this is migrating the junit tests to instrumentation
tests, but this isn't always feasible.

For example, QualityEnforcerUnitTest is really difficult to re-write as
an instrumentation test because of how it mocks out Activity behaviour
and tests toasts.
