x86/tsx: Minor cleanup and improvements
* Introduce cpu_has_arch_caps and replace boot_cpu_has(X86_FEATURE_ARCH_CAPS)
* Read CPUID data into the appropriate boot_cpu_data.x86_capability[]
element, as subsequent changes are going to need more cpu_has_* logic.
* Use the hi/lo MSR helpers, which substantially improves code generation.
No practical change.
