perf c2c: Add annotation support to perf c2c report

Browse source

Perf c2c report currently specified the code address and source:line
information in the cacheline browser, while it is lack of annotation
support like perf report to directly show the disassembly code for
the particular symbol shared that same cacheline. This patches add
a key 'a' binding to the cacheline browser which reuse the annotation
browser to show the disassembly view for easier analysis of cacheline
contentions.
