libnm: add nm_setting_option_clear_by_name()
More general purpose API for generic options of settings.

The predicate function is also nicely usable via bindings.

One question is about the form of the predicate. In this case,
it is convenient to pass nm_ethtool_optname_is_coalesce(). On the
other hand, it's not very flexible as it does not accept a user
data argument. Use NMUtilsPredicateStr here, which is not flexible
but convenient for where it's used.

* and @NM_SETTING_DIFF_RESULT_IN_B_DEFAULT, if the values are default values.
* @NM_SETTING_COMPARE_FLAG_IGNORE_TIMESTAMP: ignore the connection's timestamp
