benches: Added stack/heap measurements to bench_wt

Browse Source 
Might as well, we have the hooks already.

The only annoying this is these extra probes clutter up the `make
bench-marks` output, so split into two separate rules:

- make bench-marks
- make bench-usage

It's tempting to add disk usage as well (we have bench_helper_usage for
this purpose), but I'm not sure how to measure usage in bench_wt_seq
since it's constantly truncating.
