Crypto++ vendoring notes

• Upstream version: Crypto++ 8.9.0
• Upstream tag: CRYPTOPP_8_9_0
• Upstream commit: 843d74c7c97f9e19a615b8ff3c0ca06599ca501b
• Source: https://github.com/weidai11/cryptopp

The top-level source distribution is vendored for disconnected builds. CMake excludes upstream test programs, assembly, and algorithm-specific SIMD units.

WiiCompiled carries three small portability adaptations for its supported Clang/MSVC-ABI build:

1. config_os.h has a project-scoped opt-in around Crypto++ 8.9.0's Clang/MSVC hard stop.
2. config_int.h can avoid Clang's 128-bit division helpers, which are absent from this ABI's runtime library.
3. cpu.cpp returns inert feature-probe results when CRYPTOPP_DISABLE_ASM is set, avoiding references to the deliberately omitted x64 assembly helpers.

This configuration supplies SHA-1, sect233r1 public key derivation, ECDSA signing, signature verification, and key validation for the runtime's Wii ES crypto implementation.
