Add cpuinfo-noop.c stubs for cpufreq/cpuinfo on Android cdylib
cpuinfo-linux.c / cpufreq-linux.c are gated out for Android (bionic
doesn't ship cpu-features.h in default includes), but their exported
functions are referenced from upper layers as diagnostics. Add no-op
stubs for cpucount_linux, cpuusage_linux, frequency_linux,
{min,current,max}_scaling_frequency, cpustatetimes_linux,
current_scaling_governor, cpufreq_available_governors,
cpufreq_set_governor.
Returning 1-cpu / no-frequencies / empty-strings is safe — these are
diagnostic-only and don't drive scheduling decisions.
