RSDK-10518: Support setting globalLogger's level from config file

[aldenh-viam]

In the configuration file:

"debug": true
or
"log": [ { "pattern": "*", "level": "debug", } ]
will now display DEBUG logs for modules. Note the latter updates through config.go:UpdateLoggerRegistryFromConfig and appears to work fine as-is.

Currently, this is only available when running viam-server with -debug because:
RunServer calls config.InitLoggingSettings(logger, argsParsed.Debug):

InitLoggingSettings calls both logging.GlobalLogLevel.SetLevel and logger.SetLevel.

The refreshLogLevelInLock is called after configs are read (both initially and when updated) and is missing the logger.SetLevel update.

Does this fix the issue described in RSDK-10518? If so, do you know why? What does globalLogger.logger.SetLevel do that logging.GlobalLogLevel.SetLevel does not?
