perf/x86: Move branch classifier

Browse source

Commit 3e702ff6d1 ("perf/x86: Add LBR software filter support for Intel
CPUs") introduces a software branch filter which complements the hardware
branch filter and adds an x86 branch classifier.

Move the branch classifier to arch/x86/events/ so that it can be utilized
by other vendors for branch record filtering.
