Add configurable FFU build partition drive letters

Browse Source 
Add System, Windows, and Recovery partition drive-letter settings to the Hyper-V Settings UI, config save/load, BuildFFUVM parameters, and sample/docs. Defaults remain S, W, and R.

Validate selected letters early, log validation failures for the UI, include drive-letter metadata in VHDX cache matching, and normalize legacy malformed cache values. This only affects FFU build-time partitioning; ApplyFFU deployment letters remain unchanged.
