perf evlist: Always use arch_evlist__add_default_attrs()

Current perf stat uses the evlist__add_default_attrs() to add the
generic default attrs, and uses arch_evlist__add_default_attrs() to add
the Arch specific default attrs, e.g., Topdown for x86.

It works well for the non-hybrid platforms. However, for a hybrid
platform, the hard code generic default attrs don't work.

Uses arch_evlist__add_default_attrs() to replace the
evlist__add_default_attrs(). The arch_evlist__add_default_attrs() is
modified to invoke the same __evlist__add_default_attrs() for the
generic default attrs. No functional change.

Add default_null_attrs[] to indicate the arch specific attrs.
No functional change for the arch specific default attrs either.
