Stufe 4c (#764): Bezeichner auf Englisch - Typen, Methoden, Felder, Parameter, Locals, Testnamen

Mit Roslyn umbenannt (Verweise folgen, Zeichenketten bleiben unberuehrt).
Nicht umbenannt, weil gespeichert oder ueber die API gebunden (Stufe 4e):
Properties, Record-Parameter, Enum-Member sowie die Parameter der
Endpunkt-Handler (Routen-/Query-Bindung ueber den Namen). Die JSON-Felder
anonymer Objekte bleiben ausdruecklich benannt (JsonFilter: pfad).
