Charlotte Brandhorst-Satzkorn 3417ddc00c tailcfg: add location field to hostinfo 
This change adds Location field to HostInfo.
Location contains the option for a Country, CountryCode, City, CityCode
and a Priority. Neither of these fields are populated by default.

The Priority field is used to determine the priority an exit
node should be given for use, if the field is set. The higher the value
set, the higher priority the node should be given for use.

Updates tailscale/corp#12146
