A lot of different modem related processes require reading / writing to
the same android system properties. This CL solifies them all into
one place to avoid duplication.

android_property_manager is moved to its own folder in the root of the
modem folder. This is so that libeomservice proxy has a specific build
target to include.
Test: build, flash, check modem logs in bugreport

Since radioext has already moved to this folder, it doesn't make sense
for the base folder to be dump_modemlog. This change moves it to its
own subfolder so that we can also add more in the future.
Test: build and flash, trigger bugreport and check modem logs are there
