perf tests: Add test for PE binary format support
This adds a precompiled file in PE binary format, with split debug file,
and tries to read its build_id and .gnu_debuglink sections, as well as
looking up the main symbol from the debug file. This should succeed if
libbfd is supported.
Committer testing:
$ perf test "PE file support"
68: PE file support : Ok
