Enable HttpFormWarning feature for browser tests

Enable HttpFormWarning feature for browser tests

The HttpFormWarning is enabled by fieldtrial_testing_config.json but
that configuration is not used by the official builders, causing the
ShowFormNotSecureOnUsernameField browser test to fail when run on the
builders.

Explicitly enable the feature for the affected browser tests.

PTAL? The new browsertest was failing on the official builders because the
feature is not enabled everywhere. 

(It passed CQ and locally because the feature is enabled by
fieldtrial_testing_config.json)
