dummyflasher: Add basic WP support for opaque VARIABLE_SIZE chip

Since VARIABLE_SIZE emulated chips do not correspond to actual flash
chip models, no active protection modes are supported:
 - read_wp_cfg always returns mode=disabled,range=0,0
 - write_wp_cfg only accepts mode=disabled,range=0,0

However this is sufficient to support use cases where the user just
needs to verify that write protection is not enabled, as is the case in
some futility unit tests.
