Update Compiling for Windows following Direct3D 12 being enabled by default

The recommendation is now to leave `d3d12` to its default `yes` value,
which means installing Direct3D 12 dependencies is considered required
by default.

You can still skip the dependencies by compiling with `d3d12=no`, which matches
the behavior of self-compiled builds prior to Godot 4.6.

+By default, Windows builds of Godot contain support for the Direct3D 12 graphics

 You can install the required dependencies by running
 ``python misc/scripts/install_d3d12_sdk_windows.py``

-SCons option to enable Direct3D 12 support. This will use the default paths for
