perf hists browser: Rename perf_evsel_browser_title to a more descriptive name

Rename it to hists_browser__scnprintf_title() to better reflect that it
provides a scnprintf-like function operating on a hists_browser
instance.

This paves the way to have a non-hists_browser specific function to
scnprintf format a title with per evsel information to use in other
tools or UIs.
