1. Avoid a seperate IPC querying in to system-server to initialize the mUseBLAST flag. 2. Avoid calling property_get_bool with each BufferQueue creation. Instead we piggy-back both values inside addWindow return values. Bug: 152501005 Test: Existing tests pass Change-Id: If130560a8230f8d399cf7631264d551522939faa
