This change adds to configstore@1.0 HAL a new configuration item
for surfaceflinger; useTripleFramebuffer()
In the default implementation, useTripleFramebuffer() will return true
only if the build flag NUM_FRAMEBUFFER_SURFACE_BUFFERS is defined as 3.
Bug: 34723491
Test: build & run. log message "SurfaceFlinger FrameBuffer: ?"
should be seen.
