perf annotate: Rename to __hist_entry__tui_annotate()

perf annotate: Rename to __hist_entry__tui_annotate()

There are three different but similar functions for annotation on TUI.
Rename it to __hist_entry__tui_annotate() and make sure it passes 'he'.
It's not used for now but it'll be needed for later use.

Also remove map_symbol__tui_annotate() which was a simple wrapper.
