This pulls out the Wake-on-LAN (WoL) code out into its own package
(feature/wakeonlan) that registers itself with various new hooks
around tailscaled.

Then a new build tag (ts_omit_wakeonlan) causes the package to not
even be linked in the binary.

Ohter new packages include:

   * feature: to just record which features are loaded. Future:
     dependencies between features.
   * feature/condregister: the package with all the build tags
     that tailscaled, tsnet, and the Tailscale Xcode project
     extension can empty (underscore) import to load features
     as a function of the defined build tags.

Future commits will move of our "ts_omit_foo" build tags into this
style.

Updates #12614
