runtime: add concept up an automatic update_rate to gr::block.
When enabled, uses nitems_written/nitems_read to update the relative_rate of a block. Useful for blocks that change their relative rate based on activity in the work function. Disabled by default.
digital: PFB clock sync blocks set update_rate to True.
