Daniele Lacamera 20a838aac3 Falcon: native wolfCrypt implementation (no liboqs)

Add a complete native Falcon post-quantum lattice signature implementation to
wolfCrypt, replacing the liboqs wrapper. Full key generation, signing and
verification for Falcon-512 (level 1) and Falcon-1024 (level 5).

  - Public API wc_falcon_* / falcon_key in falcon.c wraps the native core
    (falcon_native_* in wc_falcon.c) plus wc_falcon_{fpr,fft,poly,sampler,
    codec,keygen,sign,bigint}.c. No liboqs dependency.
  - Portable, constant-time integer-emulated floating-point (fpr) backend is
    the default; opt-in per-architecture acceleration:
      --enable-falcon-double  inline native double
      --enable-falcon-asm     x86-64 SSE2 out-of-line fpr asm
      --enable-falcon-avx2    x86-64 AVX2 (4-wide) FFT
  - Division-free (Barrett) integer NTT on the verify path, so no hardware
    divide is required on Cortex-M / embedded targets.
  - Verify uses a cached twiddle-factor NTT; signing uses the FFT / ffLDL tree
    and discrete Gaussian sampler over the abstract fpr seam.
  - test.c falcon_test (KAT verify + native keygen/sign/verify roundtrip);
    scripts/falcon-interop.c and a CI workflow cross-check native<->liboqs in
    both directions.

wolfSSL CMake

This directory contains some supplementary functions for the CMakeLists.txt in the root.

See also cmake notes in the INSTALL documentation file. When building with autoconf/automake, CMake package files are installed by default under $(libdir)/cmake/wolfssl to support find_package(wolfssl). Disable with ./configure --disable-cmake-install.

If new CMake build options are added cmake/options.h.in must also be updated.

For more information on building wolfSSL, see the wolfSSL Manual.

In summary for cmake:

# From the root of the wolfSSL repo:

mkdir -p out
pushd out
cmake ..
cmake --build .

# View the available ciphers with:
./examples/client/client -e
popd

CMake Presets

The CMakePresets.json; see [cmake-presets(https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html)

Cross-platform and cross-IDE.
Standardized CMake feature (since CMake 3.19+, recommended after 3.21).
Works in Visual Studio, VS Code, CLI, CI systems, etc..

Visual Studio Settings

There's also a Visual Studio specific file: CMakeSettings.json. This the file that supports the GUI CMake settings.

See the Microsoft CMakeSettings.json schema reference

Visual Studio (2022 v17.1 and later):

Prefers CMakePresets.json if it exists.
Falls back to CMakeSettings.json if no presets are found.
Lets you override or extend presets via CMakeSettings.json.

Recommendations:

Use CMakePresets.json to define shared, cross-platform presets.
Use CMakeSettings.json to define Visual Studio-specific overrides, like:
- Custom output directories
- Specific environment variables
- *UI-related tweaks
