Reland "[UPMLoginDbSunset] Add fieldtrial testing config for the login db"

The enabled feature is deprecating the old password manager storage.
Instances of Chrome who don't fulfill the criteria (the GMS Core
version being one of them) no longer have the ability to save
passwords.

This reverts commit 72ef42a3118d1458c5b31f6362dea25cac4780ab.

Reason for reland: The tests failed on a bot running on a device
with out-of-date GMS Core. Those test suites should fake the GMS Core
version instead, so that they are not dependent on the device config.

Alternatively, they could be skipped on incompatible configurations,
but since other parts of the configuration are relevant, we probably
don't want to decrease coverage on those devices fully.
