To enable hardware acceleration, this commit ports the feature detection logic from libgcrypt. This allows us to check if the compiler supports specific assembly instructions, including SSSE3, Intel SHA extensions, SSE4.1, AVX, AVX2, AVX512, and BMI2. To simplify the initial implementation, support for x86_64 feature detection is currently limited to the x86_64 EFI target.
