libflashrom,writeprotect: add flashrom_wp_get_ranges()

The intention is that it will be kept complete, i.e. bits will be added as necessary to support new chips. The count/present fields allow unused bits to be ignored for chips that don't need them.
You're right that we'll need to add WPS for some chips.

PS22, Line 202: chip
> Isn't everything about chips? Could we just call it `flashrom_wp_config`?
I've changed it to `wp_bits`. The name is probably less important now that it is just used internally by writeprotect code, but I'm happy to change it to something else.

I've though about this more and I agree that it would be best to keep it private to writeprotect/wp_ranges code. I will move it to writeprotect.h.

Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, Sergii Dmytruk,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/58479
to look at the new patch set (#25).
Change subject: libflashrom,writeprotect: add functions for reading/writing WP settings
......................................................................
libflashrom,writeprotect: add functions for reading/writing WP settings
Two new functions are exposed through the libflashrom API:
`flashrom_wp_{read,write}_settings()`. The input/output of these
functions is a `struct flashrom wp_settings` instance, which includes
the flash protection range and status register protection mode.
This commit also adds `{read,write}_wp_bits()` helper functions that
read/write chip-specific WP configuration bits.
