libflashrom,writeprotect: add functions for reading/writing WP configs
New functions are exposed through the libflashrom API for
reading/writing chip's WP settins: `flashrom_wp_{read,write}_cfg()`.
They read/write an opaque `struct flashrom_wp_cfg` 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.
Tested: flashrom --wp-{enable,disable,range,list,status} at end of patch series
