Thread_id doesn't tell if a CPU is allowed or not.

Detect allowed CPUs only and use the first detected thread/core as the
primary thread/core of a core/package.

When detecting the primary thread/core in a core/package, current code
doesn't handle the allowed CPUs.

Abstract several functions for further fix of this issue.

for_all_cpus/for_all_cpus_2 are used for accessing the per CPU counters,

Turbostat supports "-c" parameter which limits output to system summary
plus the specified cpu-set. But some code still uses cpu_present_set to
read and dump the counters.

Introduce cpu_allowed_set for code that should obey the specified cpu-set.

Move all cstate probing related code into probe_cstates().

Note that dump_platform_info() actually dumps both MSR_PLATFORM_INFO and
MSR_IA32_POWER_CTL. MSR_PLATFORM_INFO is for pstate and
MSR_IA32_POWER_CTL is for cstate. So split dump_platform_info() and dump
MSR_IA32_POWER_CTL in probe_cstates().

AMD/Hygon platforms that don't have RAPL use 'amd_features' to describe
the platform features. Unknown Intel platforms use 'default_features' to
describe the platform features.

As none of the platform feature is set for 'amd_features' or
'default_features', there is no need to maintain both of them.

Remove 'amd_features' structure and improve the logic in
probe_platform_features().
