perf record/stat: Explicitly call out event modifiers in the documentation

Event modifiers are not mentioned in the perf record or perf stat
manpages.  Add them to orient new users more effectively by pointing
them to the perf list manpage for details.

Fixes: 2055fdaf ("perf list: Document precise event sampling for AMD IBS")
