NosCore.ClientLab: statically recompiling the NosTale client for browser tests

NosCore.ClientLab statically recompiles a user-supplied NosTale Windows client from x86 into C and WebAssembly for automated tests against a NosCore server. Ghidra and IDR provide function information, a custom lifter translates instructions, and a browser host replaces Windows graphics, audio and networking services.
