Exempt exact alarms using listener from permission

Listener alarms rely on the caller staying in valid lifecycle till the
alarm expires. In this case the caller should be encouraged to use
exact alarms for use-cases requiring timing precisions without needing
additional user consent.

Adding explicit reason codes for listener and prioritized alarms for
logging when these alarms are also exact.

Also reducing the quota of listener allow-while-idle alarms to match
other alarms that do not require permission.
