Fix Windows build type problem

[godotalgorithm]

Windows executables are presently being built with a "Debug" build type and thus debug flags rather than optimization flags, which is slowing down the distributed Windows executables for MOPAC. This is an open PR for repairing the CMake and GHA scripts to fix this problem.

The problem was that CMAKE_BUILD_TYPE was being set too late, and for whatever reason it still working on Mac and Linux even though it was technically wrong. CMAKE_BUILD_TYPE is used when the project() or enable_language() commands are used in CMake, and so it needs to be set before then.
