ipn, ipn/ipnlocal: add Foreground field to ServeConfig

Browse Source 
This PR adds a new field to the ServeConfig which maps
WatchIPNBus session ids to foreground serve configs.

The PR also adds a DeleteForegroundSession method to ensure the config
gets cleaned up on sessions ending.

Note this field is not currently used but will be in follow up work.

Updates #8489
