[BlinkGenPropertyTrees] Promote BGPT to experimental

BlinkGenPropertyTrees (BGPT) is an incremental step towards making
compositing decisions after the paint lifecycle phase. The primary
changes are to build property trees in blink and send a layer list to
the compositor, rather than building property trees in cc from a layer
tree.

This shifts time (e.g., we now run PaintArtifactCompositor and no
longer run the cc property tree builder) and will likely change
performance benchmarks.
