AlignmentMatrixControl: do not use Composite store

[ciampo]

What?

Requires #64832 to be merged first
Extracted from #64723

Refactor AlignmentMatrixControl so that it doesn't use the store from useCompositeStore to function.

Why?

See #63704 (comment)

How?

By controlling the activeId state via props.

Testing Instructions

Make sure that existing usages of AlignmentMatrixControl continue to work as expected.

In particular, make sure that the onChange callback is fired as expected, and that setting value and/or defaultValue props works like on trunk
