[scenic][ui-input] Pull out registries into separate classes

Creates separate classes for the implementations of
fuchsia::ui::pointerinjector::Registry and
fuchsia::ui::policy:accessibility::PointerEventRegistry, letting
InputSystem own instances of them instead of implementing them directly.
(Also meant to split out fuchsia.ui.pointercapture.ListenerRegistry,
but it was too closely entwined with InputSystem to be worth it)

This helps separate concerns and will let us split out unit tests
better.

No functional changes. Separate unit tests for the new classes to come
later, currently covered by the old tests.

Fixed: 74842
Test: input_unittests

Fuchsia

Pink + Purple == Fuchsia (a new operating system)

What is Fuchsia?

Fuchsia is a modular, capability-based operating system. Fuchsia runs on modern 64-bit Intel and ARM processors.

Fuchsia is an open source project with a code of conduct that we expect everyone who interacts with the project to respect.
