Reapply "Make the enabled property configurable"

Previously, I had changed some loadhook-appended property structs
to use selects instead of the "target" property struct. This seems
to not be exactly equivalent because "target" properties are merged
with the regular properties later, at the time the arch mutator runs.

With this reapplication, leave those target property structs alone
to avoid breakages, but I'll have to look into what the issue is
with them later.

This reverts commit ed5276f082.

Ignore-AOSP-First: This cl needs to be in a topic with internal-only projects, will cherrypick to aosp after.
