perf/x86/intel: Use cache cpu-type for hybrid PMU selection
get_this_hybrid_cpu_type() misses a case when cpu-type is populated regardless of X86_FEATURE_HYBRID_CPU. This is particularly true for hybrid variants that have P or E cores fused off. Instead use the cpu-type cached in struct x86_topology, as it does not rely on hybrid feature to enumerate cpu-type. This can also help avoid the model-specific fixup get_hybrid_cpu_type(). Also replace the get_this_hybrid_cpu_native_id() with its cached value in struct x86_topology. While at it, remove enum hybrid_cpu_type as it serves no purpose when we have the exact cpu-types defined in enum intel_cpu_type. Also rename atom_native_id to intel_native_id and move it to intel-family.h where intel_cpu_type lives.
