A previous version of this change also removed
system compositing of PhysicalShapeLayers on
Fuchsia. In this reland, keep using system
composting for PhysicalShapeLayers.

Prerolling a layer can have side effects. In particular, PlatformViewLayer::Preroll
will call view_embedder->PrerollCompositeEmbeddedView.
Clip layers will check whether the layer's children are all clipped and if so
will skip calling Preroll on the children. However, the Paint implementation in
these layers was always calling Paint on their children.
This could result in a call to PlatformViewLayer::Paint without a corresponding
call to PlatformViewLayer::Preroll. This translates to a CompositeEmbeddedView
call without a PrerollCompositeEmbeddedView call on the affected view_id.
The EmbedderExternalViewEmbedder implementation does not allow that.
With this change, clip layers will only call PaintChildren if the preroll
called PrerollChildren.

This reverts commit a86ef94656.
This adds more trace events to more layer operations and enhances the
trace counters for the Fuchsia vulkan surface pool to include retained
surface counts, emit stats on recycle events that might change the
surface count, and by separating counters which measure bytes from
counters which measure counts to make analysis simpler.
This is a duplicate of flutter/engine#13360 with the test switched to use the software backend instead of the GL backend.
After some debugging and testing on another GL embedder I think the issue with the test is some bug having to do with the GL implementation in the test harness specifically.

Previously the cache was disabled on whether or not PlatformViews were
globally enabled. Instead track their existence in the view hierarchy
and only disable RasterCache if a PlatformView is actually present.
This used to only be handled correctly for non-root layer backing stores. This
was mostly a side effect of the fact that we used recording canvases instead of
rendering directly into the backing store. We now use recording canvases
consistently.
