REST API: Support a broader range of JSON media types.

Previously, we only supported `application/json` which prevented using subtypes like `application/activity+json`. This allows for the REST API to `json_decode` the body of requests using a JSON subtype `Content-Type`. Additionally, `wp_die()` now properly sends the error as JSON when a JSON subtype is specified in the `Accept` header.

Props pfefferle.
Fixes #49404.
