* Introduce `SkiaObject` an object that's backed by Skia C++ objects that need to be explicitly deleted.
* Automatically delete `SkiaObject`s at the end of frame.
* Make `SkPaint` a `SkiaObject`.

Because `SkiaObject`s are deleted at the end of the frame, the object can be reused as many times as necessary within the frame. `SkPaint` in particular is a fairly expensive object. Reusing this object, for example, on `drawRRect` drops the canvas paint time by 30%.

Add a test to verify behavior discussed in b/143612326

If a new fallback font is discovered during paragraph layout, the fallback
font cache in txt::FontCollection will use that font in future layouts.

However, that cache is not available if the new fallback font needs to be
used for other characters within the current layout.  This PR adds a cache
to minikin::FontCollection and checks whether fonts in the cache can handle
a character before calling the fallback font provider.

See https://github.com/flutter/engine/pull/13257

This makes it so that the platform views can be passed
an arbitraty CreateVsyncWaiter callback that lets us inject
a vsync waiter other than just the simulated monotonic vsync waiter
that currently exists.

This earlier pattern was to use callbacks with latching.

* Split surface and canvaskit classes more

* fix licenses

* address comments

This move makes it easier to add more vsync waiters.

Since Flutter tracing is wired up to Fuchsia system level tracing (and
that includes Skia tracing within Flutter), it makes more sense to
enable Skia tracing by default on Fuchsia, and to control Flutter Skia
tracing, rely on whether Fuchsia system tracing is enabled, in progress,
and contains the "skia" category.
