This commit also fixed a broken cmake dependency with unicorn

The mingw builds aren't submitting telemetry because the curl library
they are linked against is configured to use openSSL and openSSL looks
for the certificates in the users home folder. This keeps it from
contacting web services because it can't communicate over SSL.

This commit adds a download in mingw builds that will download a
precompiled curl for mingw linked against winssl and sspi.

Now cmake relies on two submodules to copy the libraries in the proper folders

Created a new folder in Citra's root called CMakeModules that should
contain cmake functions used by the various CMakeLists.txt.
