ref(cmdk): Remove onAction prop in favor of internal action execution (#112648)

Removes the onAction prop from commandPalette which was requiring us to
redefine the test and prod logic and diminishing the value of our tests.
With this change, the action.onAction or action.to are invoked
internally by the command palette.
