Re-land r248110 "[Password Generation] Enable new UI"

Replaces key icon and associated bubble with autofill style dropdown. Changes include

- Update PasswordGenerationAgentTest
- Add interactive_uitest for new UI.
- Sync edits to confirmation password field(s).
- Update UMA stats to more accurately reflect user choices.

Updating the generation popup to match the latest mocks and implement the
editing popup will come in a later CL.

This reverts r248119 and fixes a use-after-free in
PasswordGenerationPopupControllerImpl::PossiblyAcceptPassword()
