perf tests: Move x86 tests into arch directory

Move out the x86-specific tests into tools/perf/arch/x86/tests and
define an 'arch_tests' array, which is the list of tests that only apply
to the build architecture.

We can also now begin to get rid of some of the #ifdef code that is
present in the generic perf tests.

- * test__perf_time_to_tsc - test converting perf time to TSC.
- *
- * This function implements a test that checks that the conversion of perf time
- * to and from TSC is consistent with the order of events.  If the test passes
- * %0 is returned, otherwise %-1 is returned.  If TSC conversion is not
- * supported then then the test passes but " (not supported)" is printed.
