feat: Allow customizing schema component keys

[provinzkraut]

Allow customizing the schema key used for a component in the OpenAPI schema. The motivation is to give the user an escape hatch when we inevitably generate some less than pretty looking names for deeply nested types for the sake of uniqueness.

These supplied key are enforced to be unique, and it is checked that they won't be reused across different types.

---

• Add a new schema_component_key to KwargDefinition and the Body and Parameter functions
• Add a friendly error message when keys are not unique / reused across different types
