PMUs advertise their capabilities via sysfs attribute files but
the perf tool currently parses only core(CPU) or hybrid core PMU
capabilities. Add support of recording non-core PMU capabilities
int perf.data header.

Note that a newly proposed HEADER_PMU_CAPS is replacing existing
HEADER_HYBRID_CPU_PMU_CAPS. Special care is taken for hybrid core
PMUs by writing their capabilities first in the perf.data header
to make sure new perf.data file being read by old perf tool does
not break.
