Improve Windows build support (nats-io#760)

* Improve Windows build support

Added vcpkg.json as package manifest for dependencies.
Changed the build options in CMakeLists.txt by specifying the output
directories to make sure DLLs are copied next to executables for
Windows debugging in an IDE (e.g. Visual Studio or CLion)
Disabled the build of NATS streaming since protobuf-c dependency
doesn't seem to be working properly, and it's deprecated anyway.
Further, updated .gitignore to exclude Visual Studio related files and
the 'out' directory which VS seems to use by default for build output.

* Fix ci

* Windows build workflow

* refer to nonats from the new location

* Revert NATS_BUILD_STREAMING back to ON

* Revert NATS_BUILD_STREAMING back to ON

* Fixed warnings in micro examples

* Moved the Windows job under on-pr-...

* job names that make more sense

* refactoring, may break again

* Revert "refactoring, may break again"

This reverts commit d40de83.

* more names

* Warnings as errors

* Warnings

* removed default run in case it affects the windows build

* turn warnings off for test
