The idea is to open up patching possibilities. Right now unless a section explicitly sets patchable?: true it is forbidden to add any entities with patches to it.

This change allows adding entities that have the same target as at least one of preexisting entities in a section.

It will allow to easily provide shortcut/alias entities with extensions in ash-compatible way, so that auto-complete and do end syntax for options can work out of box for those aliases.

patchable?: true still needs to be set to allow adding entities with arbitrary targets.

Don't know if I can put check mark on unit tests, but the only place in tests where patchable?: true was used can now omit that option since a test extension was adding the same target thing (preset).
