Description

Currently, configure.win and tools/winlibs.R have two ways of finding the Arrow C++ library:

1. If RWINLIB_LOCAL is set, it gets it from that zip file
2. If not, it downloads it

Enable and document a third option for the case when the C++ library has been built locally. This will enable R package developers using Windows machines to make changes to code in the C++ library, build and install it, and then build the R package using it.
