[flexible-schema] Add createOne/createMany with upsert to graphql query runner (#7041)

## Context
This PR introduces createOne/createMany through the new graphql query
runner.
Trying to use twentyOrm wrapper as much as possible, in this case here
the args are already converted from "metadata-like" structure (including
composite fields) as graphql input to typeorm / raw columns (I had to
introduce a little fix there).

Keep in mind that I'm not using the new graphql query runner parsing
classes here, especially the selected-fields part, because typeorm
already returns all the record columns in the InsertResult object
(including default values such as id, createdAt, ...). That also means
relation objects will be returned as NULL in the gql response but we
don't handle nested creation for the moment so it should be fine.

Note: also removing the feature flag from findOne/findMany
