codec2: switch perferred linear allocator type by pool mask
The preferred linear buffer allocator could be switched between Gralloc BLOB
and ION by runtime property "debug.stagefright.c2-poolmask". ION should be
chosen as fallback allocator type if the pool mask property doesn't enable
the bit of Gralloc BLOB.
Bug: 143180475
Test: make libcodec2_vndk
Test: make libsfplugin_ccodec
