B3-Express: statically recompiling Bayonetta 3 for Windows

B3-Express ports Bayonetta 3 v1.2.0 to Windows by recompiling its ARM64 code to x86 with a modified ScarletNX runtime. An NVN-level Vulkan renderer draws the game, and a launcher checks an extracted game dump, copies its files and compiles the code on the user's PC. The repository also contains diagnostic notes on rendering and runtime issues.
