As a workaround to a caching bug, we rename
the old HsumConfigOverlay to HsumDefaultConfigOverlay.
Bug: 357828774
Test: manual (flash build from a week ago, flash this build without
wiping, make sure the system boots)
Flag: EXEMPT refactor (and bug fix)

* Moves HSUM configuration to AOSP (so it can be used by anyone, and can
exist in generic systems)
* Defines a variable for selecting HSUM-variant products, that is, a way
to select an alternate version of packages when required on HSUM
devices.
* Utilises this mechanism to use an alternative version of
TelephonyProvider (that has per-user databases) on HSUM devices.
Note that HSUM refers to Headless System User Mode, which is a
particular device mode in which user 0 isn't a human user.
