Split time_zone_distro static library in two

Split time_zone_distro static library in two. Cherry
picking an earlier change to aosp/master revealed that
aosp/master appears to build system-stubs from live code
there.

stubs -> telephony -> services -> time_zone_distro -> stubs

time_zone_distro is support code shared by the platform
and a provider used by an unbundled app. The two cases can be
split to ensure the cycle is broken.
