Use non-mangled type names in nvbench output

[davidwendt]

Description

Uses the NVBENCH_DECLARE_TYPE_STRINGS feature to produce readable type names in the nvbench output.
Example previous output for cudf::timestamp_ms would appear like this:

| cuda::std::__4::chrono::time_point<cuda::std::__4::chrono::system_clock, cuda::std::__4::chrono::duration<long, cuda::std::__4::ratio<1l, 1000l> > > | 100000 |  23840x | 25.138 us | 21.98% | 20.979 us |  9.54% | 4.767G |  38.134 GB/s |  4.38% |

Adding the nvbench name feature changes this to:

| cudf::timestamp_ms | 100000 |  24752x | 24.387 us | 21.58% | 20.208 us | 3.79% | 4.948G |  39.588 GB/s |  4.55% |
