[PATCH 0/1] MR6299: ntdll: Determine the available address space dynamically on all architectures

[theofficialgman (＠theofficialgman)]

Resolves issue https://gitlab.winehq.org/wine/wine/-/merge_requests/3598#note_75871

The host address space limit may not be `0x7fffffff0000` on any architecture (eg: ARM64). Such architectures can fully emulate x86_64 Wine (eg: QEMU, FEX, BOX64) and need to have their host address space detected. Implementing the detection regardless of the Wine build architecture should not regress anything.
