Samsung's Korean keyboard has a bug where it always attempts to combine
characters based on its internal state, ignoring if and when the cursor
is moved programmatically. EG typing "ㄴㅇ" and then moving the cursor
back to the front of the text and typing "ㄴ" again would result in
"ㄴㅇㄴ", not "ㄴㄴㅇ".

Fully restarting the IMM works around this because it flushes the
keyboard's internal state and stops it from trying to incorrectly
combine characters. However this also has some negative performance
implications, so we only apply the workaround on Samsung devices set
to use Korean input.

This also effectively disables the feature on Samsung keyboards that
allowed users to re-open a composing region for previously typed
characters. See https://github.com/flutter/flutter/issues/29341#issuecomment-531283508.

Fixes flutter/flutter#29341.

On Fuchsia, add a build flag for compositing OpacityLayers using the system
compositor vs Skia, which exposes a fastpath for opacity via Scenic.
This will only work under certain circumstances, in particular nested
OpacityLayers will not render correctly!

On Fuchsia, add a build flag for compositing PhysicalShapeLayers using
the system compositor vs Skia. Set to off by default, which restores
performant shadows on Fuchsia.

Remove the opacity exposed from ChildView, as that was added mistakenly.

Finally, we centralize the logic for switching between the
system-composited and in-process-composited paths inside of
ContainerLayer. We also centralize the logic for computing elevation
there. This allows the removal of many OS_FUCHSIA-specific code-paths.

Test: Ran workstation on Fuchsia; benchmarked before and after
