win, build: add documentation support to vcbuild

Adds `doc` option to vcbuild.bat which will install node-doc-generator
dependencies and build the documentation in the %config%\doc folder.

Adds `lint-md-build` option which will download markdown linter.

Adds `lint-md` option, included by default in `lint` and `test` options
which will run linter on the markdown files in the doc folder.
