fix(ivy): queries not being inherited from undecorated classes (#30015)

Browse Source 
Fixes view and content queries not being inherited in Ivy, if the base class hasn't been annotated with an Angular decorator (e.g. `Component` or `Directive`).

Also reworks the way the `ngBaseDef` is created so that it is added at the same point as the queries, rather than inside of the `Input` and `Output` decorators.

This PR partially resolves FW-1275. Support for host bindings will be added in a follow-up, because this PR is somewhat large as it is.
