doc: Improve windows build instructions using Linux subsystem
I did a build on a windows 10 laptop and took notes, and tried
to improve the document:
- It's the Linux subsystem for Windows, not the other way around.
- Split out dependencies: general ones, 64-bit, 32-bit. Remove the
reference to `build-unix.md`, easy enough to be self-contained.
- Place 64-bit instructions first. 99% will want these.
- Installation instructions: recommend using `/` for prefix, same as we
do on gitian builds. This will allow copying the files to a usable
(from Windows) place using just `make DESTDIR=...`.
- Remove double spaces / consistent width reformatting.

the protobuf dependency. If this occurs, re-run the command with sudo. This is likely
a bug with the Windows Subsystem for Linux feature and may be fixed with a future update.
