WIP Remove support for legacy logging

[mkcp]

Description

WIP: two major categories of work to finish here:
1: Fully log-format="legacy" while ensuring message is still set up properly to print non-log messages like Yaml and tables.
2: Chase down every message log statement, spinner, and progress bar in the main zarf codebase. This involves a bunch of changes in packager(1) but should be a net-zero change in behavior for any user not running --log-format=legacy.

The plan is: get it compiling, then rip out the CLI layer, then chase down remaining logs and any debug coverage we might have missed the first go around.

TODO: Document and flag all breaking changes.
