fix(EntityResource|Query\Filter): path validation of filters needs to be aware of computed fields

We need to validate the filter path before executing it (or properly catch and serialize the exception if the entity query system throws one) when attempting to filter by a computed field.

Background:

While considering #2916074: [PP-1] Test coverage: FieldResolver: path validation for computed fields, I realized that the field resolution performed in Context\FieldResolver doesn't consider that filtering does not work for computed fields and will happily resolve the path. However, it is also does not seem like the right place to perform that validation. Either the Query system should perform the validation or EntityResource::getCollection should try/catch the query execution.
