Revisit handling dependent DLLs on Windows

[oleksandr-pavlyk]

I worry that this will not be sufficient for downstream consumers -- eg. a project using nvbench might fail to find these at runtime without the user reconfig'ing their path manually.

Here's how we handled this "back in the day" before we yanked msvc the first time. It copied the dependent dlls into same dir as nvbench's binaries, so that transitive linking should work without extra setup (IIRC).

It might be a good idea to point an agent at this PR and the following tag/commits to see if there's anything else that might be worth restoring. I can't remember if I mentioned these before:

tag pre_msvc_drop: https://github.com/NVIDIA/nvbench/blob/pre_msvc_drop
Commit that removed MSVC: 93ea533 (Part of #200)
