perf annotate: Return arch from symbol__disassemble() and save it in browser 



In annotate browser, we will add support to check fused instructions.
While this is x86-specific feature so we need the annotate browser to
know what the arch it runs on.

symbol__disassemble() has figured out the arch. This patch just lets the
arch return from symbol__disassemble and save the arch in annotate
browser.
