Ipp-crypto

- Added `FIPS_CUSTOM_IPPCP_API_HEADER` build flag to support FIPS self-tests for a specific use case when Custom Library Tool is used with custom prefix for IPPCP API.

- Added single-buffer implementation of Leighton-Micali Hash-Based Signatures(LMS) algorithm, verification part.
- Added support of Clang 16.0 compiler for Linux.
- Added examples of AES-GCM Encryption/Decryption usage.
- AES-GCM algorithm with Intel® Advanced Vector Extensions 2 (Intel® AVX2) vector extensions of Intel® AES New Instructions (Intel® AES-NI) was optimized.

- Minimal supported BoringSSL version was increased to [45cf810d](https://github.com/google/boringssl/archive/45cf810dbdbd767f09f8cb0b0fcccd342c39041f.tar.gz) tag.

- Added the verification part of eXtended Merkle Signature Scheme (XMSS) algorithm.
- Added FIPS-compliance mode for the library. More information can be found in the [Intel(R) IPP Cryptography FIPS Guide](./README_FIPS.md).

- Added optimized RSA-2048 code for multi-buffer (8 buffers) Intel® AVX-512 implementation.
- Added Intel® Advanced Vector Extensions 2 (Intel® AVX2) vector extensions of Intel® AES New Instructions (Intel® AES-NI) optimization for AES-GCM algorithm.
- Changed the minimal supported OpenSSL version to 3.0.8 since 1.1.1 is not supported since September 2023.
- Raised the minimal CMake version to 3.18 since this is the minimal version that supports OpenSSL 3.0.8: https://cmake.org/cmake/help/latest/module/FindOpenSSL.html.

- Crypto Multi-buffer library was extended with XTS mode of SM4 algorithm.
