refactor: unify property function implementations

Rather than reimplementing the property functions in two different languages - and potentially having compatibility issues - standardize on golang for the implementation through the use of a generated binary.

This also implements all the list functions for use with shell-based plugins.

Note that the interface to the prop binary is experimental, and it should not be used directly.
