tools headers: Synchoronize x86 features UAPI headers

Sync tools/arch/x86/include/asm/{cpu,disabled-,required-}features.h with
the changes in:

  2961298e ("x86/cpufeatures: Clean up Spectre v2 related CPUID flags")
  20ffa1ca ("x86/speculation: Add basic IBPB (Indirect Branch Prediction Barrier) support")
  5d10cbc9 ("x86/cpufeatures: Add AMD feature bits for Speculation Control")
  fc67dd70 ("x86/cpufeatures: Add Intel feature bits for Speculation Control")
  95ca0ee8 ("x86/cpufeatures: Add CPUID_7_EDX CPUID leaf")
  a511e793 ("x86/intel_rdt: Enumerate L2 Code and Data Prioritization (CDP) feature")
  4fdec203 ("x86/cpufeature: Move processor tracing out of scattered features")
  c995efd5 ("x86/retpoline: Fill RSB on context switch for affected CPUs")
  76b04384 ("x86/retpoline: Add initial retpoline support")
  99c6fa25 ("x86/cpufeatures: Add X86_BUG_SPECTRE_V[12]")
  de791821 ("x86/pti: Rename BUG_CPU_INSECURE to BUG_CPU_MELTDOWN")
  6cff64b8 ("x86/mm: Use INVPCID for __native_flush_tlb_single()")

None will entail changes in the tools/perf/, synchronizing to elliminate
these perf build warnings:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/required-features.h' differs from latest version at 'arch/x86/include/asm/required-features.h'
