Refactor RecordSingleSelect and RecordMultiSelect to be synchronous (#10469)

## Context
We are experiencing a lot of re-rendering / flash on MultiRecordSelect /
SingleRecordSelect / RelationPicker.

This PR is a first step to refactor this components

## Scope

Only move files to uniformize and prepare for the upcoming refactoring

## Vision
- SingleRecordPicker
- MultipleRecordPicker
- sharing RecordPicker tooling (RecordPickerComponentInstanceContext,
searchState)

Used in other areas:
- RelationPicker (which is actually only a subcomponent of
RelationToOneFieldInput)
- RelationFromManyFieldInput
- WorkflowRelationFieldInput
- etc.

+ remove all effects
+ migrate to the latest APIs
+ make a pass on re-renders to remove them completely (we likely need to
use a bit more familyStates here)
