Prevent glDeleteQueries from deleting a live Query

glDeleteQueries() instantly deletes all the es2::Query objects
passed as arguments to this function. If some of these queries
are still being used by the renderer, this will result in a use
after free error. To solve this issue, sw::Query is now a also
ref counted object.
