Conduit: Convert nearly all unstable methods to stable
Summary:
All these "unstable" Conduit API methods have had this status for at least ten years now.
Thus in reality they are neither new, nor subject to any planned changes, nor have they actually been "unstable" over the last years.
Thus remove the `getMethodStatus()` functions returning `METHOD_STATUS_UNSTABLE` from them.
Per their parent class, `getMethodStatus()` returns `METHOD_STATUS_STABLE` when not overwritten.
Exclude `NuanceConduitAPIMethod` from this patch, as that application is a prototype and thus unstable.
Closes T16313
Test Plan:
Go to one of those endpoints, e.g. http://phorge.localhost/conduit/method/macro.creatememe/, and do not see anymore
`Stability - Unstable Method: This method is new and unstable. Its interface is subject to change.`
