 * This function logically combines an array of simple schemas (schemas that contain no compositions)
 * in preparation for conversion to `IncrementalDataSchema`. This is akin to "multiplying" all of the schemas,
 * to continue our math analogy. The result is a single simple schema, which is easier to work with.
 *
 * How fields are combined depends on the field. For fields like `title` and `description` where
 * it doesn't make sense to combine, we just take the last. For `required` we combine arrays,
 * for `maximum` we take the minimum value, etc.
 *
 * @param schemas An array of simple schemas to combine
 * @param componentSchemas The value of `document.components.schemas`. In this function, it is only used to check if properties are readOnly/writeOnly
 * @param location Whether the schema is part of the request, response, or neither. Used for filtering readOnly/writeOnly properties
 * @returns A single simple schema that satisfies all the input schemas
