REST API: Filter responses based on the `_fields` parameter, before data
is processed.
Historically, the REST API would generate the entire response object,
including running expensive filters, then it would apply the `_fields`
parameter, discarding the fields that weren't specificed.
This change causes `_fields` to be applied earlier, so that only requested
fields are processed.
Merges [43087] to the 4.9 branch.
Props danielbachhuber.
See #43874.
