Respect 'default_option_' filters during early sanity checks in `add_option()` and `update_option()`.

`add_option()` and `update_option()` both call `get_option()` to compare the
value passed to the function with any existing value for the given option name.
When a `'default_option_'` filter is in place to change the default value of
an option, `add_option()` and `update_option()` ought to check against the
filtered value, rather than a hardcoded `false`, in order to determine whether
a prior value exists.

Props GregLone, tyxla.
Fixes #31047.
