refactor(multiple): Clean up afterRenderEffect usage across angular aria

[adolgachev]

Across angular-aria afterRenderEffect was being used as a general-purpose synching hook. Also, a phase was not specified so it always was defaulting to the mixedReadWrite phase which is not as performant and unnecessary in all the cases.

This PR cleans up the usage by:

• Swapping to effect when only internal state is being updated
• Using write mode whenever necessary to write to the DOM (primarily focus updates)
• Using read mode when not necessary to write but need to update state post render
• Other as appropriate clean up to use computed instead of an effect

See https://angular.dev/guide/signals/effect#render-phases for background.
