perf test: Move each test suite struct to its test

Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.

Committer notes:

Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

perf evlist: Rename struct perf_evlist to struct evlist

Rename struct perf_evlist to struct evlist, so we don't have a name
clash when we add struct perf_evlist in libperf.

Committer notes:

Added fixes to build on arm64, from Jiri and from me
(tools/perf/util/cs-etm.c)

perf time-utils: Add support for multiple explicit time intervals

Currently only a single explicit time range is accepted. Add support for
multiple ranges separated by spaces, which requires the string to be
quoted. Update the time utils test accordingly.
