fix(Scripts/Misc) CanExecuteCommand renamed and moved to be executed for all commands. (#19081)

* Fix CanExecuteCommand only being executed on command failure.

* Updated for style guide.

* Removed pointless hook call.

* Modified the name of the hook to better reflect function and moved the call to trigger for non-existent commands.

* Updated to OnTryExecuteCommand because Foe has a special place in my heart.

* Forgot to change these 2 areas.
