feat: Global logger functionality

[Kile-Asmussen]

Implements #3346

GitHub has accidentally removed the ability to edit PR titles, and I forgot the "feat:" tag in the title. (EDIT: Thanks @utpilla)

Changes

Adds the global::logs module containing:

• Dyn-compatible wrapper traits for LoggerProvider, Logger, and LogRecord
• Boxed dynamic-dispatch versions of Logger and LogRecord: BoxedLogger, BoxedLogRecord
• A global dynamic-dispatch LoggerProvider: GlobalLoggerProvider
• Helper functions

All of this functionality is analogous to the other global modules.

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
  • N/A: none of the other global modules have tests
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
• Changes in public API reviewed (if applicable)
