VRR: Allowlist for small area detection

Add a allowlist mechanism for suppress frame rate when small area.

In this patch, we will keep a array list to record pkg name which
want to apply the small area detection for suppressing frame rate
and its threshold value of small area ratio.

In framework, we will check all pkg uid by pkg name from
package manager and call a native function which include uid and
threshold.

In SF native, it get the threshold of uid and we will save them
as a map, and it will used to check should it apply small area
detection and what threshold it should use.
