Rename appfunctions-runtime to appfunctions-service

This is part of the package restructuring process for AppFunctions
Jetpack. The goal is to make a layered structure for developers to start
from any layer depends on their requirements. And also make sure the
package name matches the module name.

appfunctions-service module would be the module that helps to expose
AppFunctions with Jetpack defined AppFunctions runtime.
