Resolve native LMDB assets by target intent (#205)

Select the native runtime asset using RuntimeIdentifier, then PlatformTarget,
Prefer32Bit, then the build host. Map osx-x64 to the package's osx layout.
Skip host-native flat copies for RID-less class libraries so they cannot
poison cross-RID publish of a consuming app.

Fixes #205
