libflashrom: Allow getting the progress_state from the flashctx

External users of the libflashrom API cannot peek into the abstract
flashrom_flashctx structure, unlike the local CLI. Provide some API to
get the flashrom_progress struct from a flashrom_flashctx.

This allows fwupd to use the new flashrom_set_progress_callback() API
without using a global variable with the callback data.
