perf annotate browser: Allow navigation to called functions
I.e. when in the annotate TUI window, if Enter is pressed over an
assembly line with a 'callq' it will try to open another TUI window with
that symbol.
This is just a proof of concept and works only on x86_64, more work is
needed to support kernel modules, userland, other arches, etc, but
should already be useful as-is.
