Chris Roberts 61c36bdef7 [winsvc] Add support for Windows Eventlog (#26441) ...

Defines a `winsvc.Event` type which can be sent using the `winsvc.SendEvent`
function. If nomad is running on Windows and can send to the Windows
Eventlog the event will be sent. Initial event types are defined for
starting, ready, stopped, and log message.

The `winsvc.EventLogger` provides an `io.WriteCloser` that can be included
in the logger's writers collection. It will extract the log level from
log lines and write them appropriately to the eventlog. The eventlog
only supports error, warning, and info levels so messages with other
levels will be ignored.

A new configuration block is included for enabling logging to the
eventlog. Logging must be enabled with the `log_level` option and
the `eventlog.level` value can then be of the same or higher severity.
