version: add a feature names array to curl_version_info_data

Field feature_names contains a null-terminated sorted array of feature
names. Bitmask field features is deprecated.

Documentation is updated. Test 1177 and tests/version-scan.pl updated to
match new documentation format and extended to check feature names too.

Closes #9583

\fIfeatures\fP is a bit mask representing available features. It can
have none, one or more bits set.
The use of this field is deprecated: use \fIfeature_names\fP instead.
The feature names description below lists the associated bits.
\fIfeature_names\fP is a pointer to an array of string pointers, containing the
names of the features that libcurl supports. The array is terminated by a NULL
entry. Currently defined names are:
