[PATCH 0/2] MR4396: ntdll: Add Disable8dot3Filenames registry key

[Pedro Nishiyama (＠nishiyama)]

The current hash function can cause collisions in some applications, as described in https://gitlab.winehq.org/wine/wine/-/merge_requests/4244.

But we can't just change the hash function without breaking existing prefixes. (https://gitlab.winehq.org/wine/wine/-/merge_requests/4244#note_50530)

Windows has a registry key to disable the creation of new 8.3 Filenames, these changes should mimic this feature.
