perf: Add PMU_FORMAT_ATTR_SHOW
The macro PMU_FORMAT_ATTR facilitates the definition of both the "show"
function and "format_attr". But it only works for a non-hybrid platform.
For a hybrid platform, the name "format_attr_hybrid_" is used.
The definition of the "show" function can be shared between a non-hybrid
platform and a hybrid platform. Add a new macro PMU_FORMAT_ATTR_SHOW.
No functional change. The PMU_FORMAT_ATTR_SHOW will be used in the
following patch.
