Subject: meson: verify that d3d12.h exists when building the d3d12 driver
X-Git-Tag: upstream/21.0.0~2642

meson: verify that d3d12.h exists when building the d3d12 driver

Without this header-file, we can't build the driver. So let's verify
that it exists, and can be used by the C++ compiler.

This should make it a bit more clear what's wrong if someone attempts to
build this using MinGW or on Linux.
