Windows: Fix failing tests due to missing manifest.

Tests were missing a manifest, and were importing the
wrong version of Microsoft.Windows.Common-Controls
causing blenloader_test, bmesh_core_test and alembic_test
to fail due a loader error.

Fix T71342: macOS does not always use the discrete GPU for Blender

This reverts commit 3d9cc4d3f174d01c96d65a4e9cd751699bcb8744. The commit
message and intent behind the commit is unclear. We generally want the
discrete GPU to be used for best performance, not the integrated GPU.

Cleanup/Windows: Separate out the MS-CRT into a subfolder

In older versions the ms crt was only a few dlls, in recent versions
this jumped to over 40 leading to quite a bit of clutter in our
bin folder.

This change moves the CRT into its own folder.

For developers that generally already have the runtime globaly
available on their machine, there is a new cmake option
(WITH_WINDOWS_BUNDLE_CRT, default ON) that you can use to toggle
installing the runtime to the blender bin folder, and save some
time during the initial build, this option is off by default for
only the developer profile.
