Rootdir: Add more asan.options support
Extend the asan.options file to read binary-specific configuration
from files out of /system. For early services, the system image
location is important as /data may not be available when they are
started.
Add a template that turns most sanitization off. At this point in
time, it is, however, impossible to get to a zero overhead state
after the fact. The template is meant to adapt a build after the
fact, and work around issues with LOCAL_SANITIZE := never.
Add a Make variable and rule copying the template to the path and
name expected by ASAN. Add SANITIZE_LITE to automatically add a
large set of options files.
