These are now owned by the stdrel stopping criterion, and should not be exposed directly in the benchmark/state/etc APIs.
This will affect users that are calling
`NVBENCH_BENCH(...).set_min_time(...)` or
`NVBENCH_BENCH(...).set_max_noise(...)`.
These can be updated to
`NVBENCH_BENCH(...).set_criterion_param_float64(["min-time"|"max-noise"], ...)`.
The string used when constructing a summary is no longer a human
readable name, but rather a tag string (e.g. "nv/cold/time/gpu/mean").
These will make lookup easier and more stable going forward.
name vs. short_name no longer exists. Now there is just "name", which
is used for column headings. The "description" string may still be
used for detailed information.
Updated the json tests and compare script to reflect these changes.
