ext/standard: request_parse_body - change invalid content-type header exception to RequestParseBodyException

Currently, `request_parse_body` function throws an `InvalidArgumentException` exception if the request
`Content-Type` header is invalid or of an unknown type such as `application/json`.

To make this consistent with other exception conditions, this changes the exception type from
`InvalidArgumentException` to `RequestParseBodyException`.
