This adds:
Adds CRT aware file suffix
Per config build dir
Out-of source build dir
Variant only CPPPATH
Precompiled header for MSVC
This improves the build time a lot.
The following steps were ran in order once before and after this PR:
Iterative builds are way faster, saving up to 96% on incremental builds.
It stores object files not next to source files anymore but stores them in a separate build directory which different directories for different build configurations. This means if you compile a debug build, then a release build and then a debug build the second debug build is fast now because the object files of the last debug build were still kept.
On Windows one issue was that obj files did not have the CRT (MD/MT) in their file names which is now added. On windows if you build and run the simulations tests they build with MT, the GDExtension builds with MD though. Building the extension after the tests causes a compile error as it tries to reuse the object files that were built with the wrong CRT instead of rebuilding them.
