perf annotate: Factor out evsel__get_arch()

Browse Source 
The evsel__get_arch() is to get architecture info from the environment.

It'll be used by other places later so let's factor it out.

Also add arch__is() to check the arch info by name.

Committer notes:

"get" is usually associated with refcounting, so we better rename this
at some point to a better name.
