Binary dependency changes

[maleadt]

Couple of changes:

• expose the runtime library -- some users require it, https://discourse.julialang.org/t/shared-c-dependencies-and-artifacts/68525
• use cudart for detecting the toolkit version, not ptxas
• remove the version database, users with local toolkits should provide unversioned (development) libraries
• ... except for Windows, where libraries are always versioned. brute-force the name there.
