Force HALs to explicitly enable legacy method for clearing buffer caches
Some HAL implementations can't support setLayerBuffer multiple times to
clear the per-layer buffer caches. Therefore, default this behavior to
disabled, and allow HALs to explcitily enable this behavior to obtain
the necessary memory savings.
Test: play videos with both true and false on both HIDL and AIDL
