x86/64: 6.12: 6.18: enable performance related options

Browse Source 
Enable Turbo Boost Max 3.0 (INTEL_TURBO_MAX_3) to allow the kernel
scheduler to utilize preferred cores on modern Intel CPUs. This has
no effect on AMD systems.

Enable core scheduling (SCHED_CORE) to provide safer SMT task
placement and better isolation. While it can reduce peak throughput
slightly, it improves scheduling correctness on heterogeneous cores
and works across both Intel and AMD.

Enable the accelerated GHASH implementation using the CLMUL instruction
(CRYPTO_GHASH_CLMUL_NI_INTEL). This provides substantial performance
improvements for AES-GCM workloads (e.g. TLS, IPsec, OpenVPN) on CPUs
with the pclmulqdq instruction. Supported on both modern Intel and AMD
processors; falls back gracefully on older CPUs.

Run-tested twice, once with the 6.12 series and again with the 6.18.

Build system: x86/64
Build-tested: x86/64-glibc
Run-tested: x86/64-glibc (Intel N150 based box)
