SurfaceFlinger: Set property in StartPropertySetThread during init

This is similar to ag/1849505/ (see b/34499826), which by setting
property in a separate thread, that CL aims to avoid slow initialization
in SurfaceFlinger::init where SurfaceFlinger is waiting on
property_service.

There is new property_set() call added, and this CL is to move it to the
StartPropertySetThread.

Bug: 63844978
Test: on taimen with simulated delay ag/2562492/
