feat: migrate package create to slog

[mkcp]

Description

This PR:

• Adds contributor QOL improvements:
  • sloglint
  • New formats: devslog (via --log-format="dev") and console-slog (via --log-format="console")
• adds WithContext to packager.Packager and stores a context on it so we can log in its New() which has some load bearing logging. This is intended as a workaround.
• Makes an empty log format, the default, --log-format="" == "none. So slog must be directly enabled.
• Adds setup functions for both message and logger in cmd/root and feature flagging for disabling message and using logger.
  • When a log-format is provided, setupMessage() ensures PTerm output is discarded and sets the values for --no-progress, and --confirm.
• Adds structured logging outputs throughout zarf package create
• Marks TODOS on message calls in Create stating they're deprecated

You will need to edit cmd.Execute to slog an error message
