formatting: First round of cleanup

[lucas-manuel]

Updates

• General formatting
• Update to solc 0.8.22 to remove unchecked { ++i }
• Remove redundant getters in favour of public state variables
• Update natspec formatting
• Abstract away repeated code in _cancelTransaction and _executeTransaction to _removeActionFromQueue
• Use early exit returns where possible
• Use ternary operators where possible
• Do some if statement formatting to improve readability
• Add section labels
• Reorder some view functions
• Update _actionsSetCounter to actionsSetCount so it makes more sense as a public function
• Update _queuedActions to isActionQueued and get rid of redundant isActionQueued view function

Open Questions

What should we say instead of misc functions? Do we need executeDelegateCall anymore?

LGTM. executeDelegateCall is needed to supply an ETH msg.value for a delegate call.
