[PATCH 13/14] perf c2c: add TAB key to switch to function view

[Jiebin Sun]

Wire up the TAB key in the cacheline browser to launch the function
view browser via perf_c2c__browse_function_view(). This allows users
to switch between the traditional cacheline view and the new
function-level sharing analysis view.
