[WIRELESS]: Refactor wireless Kconfig.

This patch refactors the wireless Kconfig all over and already
introduces net/wireless/Kconfig with just the WEXT bit for now,
the cfg80211 patch will add to that as well.

-          Saying Y here also enables the Wireless Extensions (creates

-          Extension is a generic API allowing a driver to expose to the user
-          space configuration and statistics specific to common Wireless LANs.
-          The beauty of it is that a single set of tool can support all the
-          variations of Wireless LANs, regardless of their type (as long as
-          the driver supports Wireless Extension). Another advantage is that
