* Revert "Dynamically determine whether to use offscreen surface based on need (#13976)"
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.

SkiaUnrefQueue should be empty at destruction time. If the queue is nonempty,
then there will be a pending drain task that will hold a reference to the
queue. The queue can only be destructed after the drain completes and the
reference is dropped.
Drains must only be done on the queue's task runner thread, which may not be
the thread where the queue is destructed.
