…1.3 (#870)

* chore(deps): update dependency com.google.cloud:libraries-bom to v26.1.3

* 🦉 Updates from OwlBot post-processor

…16 (#872)

* Making query generic and moving all the entity records related concerns to an internal RecordQuery interface

* fixing lint

* Making getType an internal function

…lity (#876)

This change introduces a component called ProtoPreparer which will be used to populate the protos from the domain objects. In the upcoming count aggregation feature, aggregation query will be acting upon StructuredQuery and GqlQuery and hence need to populate the protos of those queries **again**.  For that reason _ProtoPreparer_ component will have the responsibility to populate the protos and be reused in multiple usecases.

_Note: This PR is intended to trim down the changes done as part of #823 ._
