types(inferrawdoctype): avoid adding _id to nested paths and handle _id: false in options + schema definition

[vkarpov15]

Summary

InferRawDocType<> currently adds _id whenever the schema definition is a record, which means nested paths get _id. We also need to handle _id: false in the schema definition.

Pull request overview

Updates InferRawDocType<> typing logic so nested schema-definition objects don’t incorrectly get _id added, and so subdocument definitions with _id: false are respected.

Changes:

• Adjust ResolveRawPathType handling for record schema definitions to avoid adding _id for nested paths and to honor { _id: false }.
• Update an existing type assertion in schema.create tests to reflect the new nested-path behavior.
• Add new type tests covering nested paths vs subdocuments and _id: false subdocuments.
