The password manager and the form autofill feature were listening for events on text input elements by registering a listener on each element. This is slowing down the page load.

This CL changes that to only 1 listener on the body of the page, that forwards the events to element specific listeners.

BUG=None
TEST=Run the test shell unit tests
