Moraea non-Metal Frameworks

The core of the non-Metal patches: wrappers for downgraded frameworks, consisting of a mixture of autogenerated stubs and handwritten shims.

build

Run Dependencies.tool to fetch dependencies from GitHub, or set MORAEA_LOCAL_DEPENDENCIES=1 to use local versions. Run Build.tool to generate binaries in the Build subfolder.

Most users will want to just use OCLP, which includes stable versions of these fixes.
