grpc-js: reject invalid Content-Type requests
This commit implements the following portion of the spec:

If Content-Type does not begin with "application/grpc",
gRPC servers SHOULD respond with HTTP status of
415 (Unsupported Media Type). This will prevent other
HTTP/2 clients from interpreting a gRPC error response,
which uses status 200 (OK), as successful.
