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 old implementation was scattered and ad hoc. This one is slightly
less so.
More importantly, refactoring to this design will make it easier to
add device traversal.
Allow types in a type_axis to be masked out, skipping all
benchmark configurations that use a masked out type.
This will allow the axis to be modified at runtime with CLI args.
Requires various changes to support mutable axes.
