Update NetSurf following 3.0 release

* All the packages have changed version
 * Cleanup the dependencies to avoid repeating transitive ones
 * libxml is not required anymore (libdom replaces it everywhere)
 * on the other hand, NetSurf build uses perl html::entities. Added a bep for it.
 * Also adjusted the licences. While NetSurf is still GPL/MIT+OpenSSL exception, all the other libs are plain MIT, with various copyright holders.
