libflashprog: Introduce new probing API flashprog_flash_probe_chip()
This new probing API acts about the same as the old one, except that
it accepts a `struct flashprog_chip *` handle instead of a chip name.
Under the hood, however, it uses our new bus probing directly.
We introduce a new function, flashprog_flash_prepare_context(), that
creates a flash context from a probed chip, and the bus it was found
on. This will be the single place that creates flash contexts in the
future.
