Make YAML Linter validate server/client-only components (#26809)

* YAML Linter now validates invalid fields in server-only and client-only components

* Update to change in engine PR

* Use reflection manager to get the lists of client/server assemblies.

Also made it use a hashset on type instead of the previous code.

* I'm dumb my bad.

* Fix 2 errors that snuck through, showing why we need this.
