Some unofficial builds running closer to upstream created a Documents ->
My Documents symlink. We would then create a My Documents -> Documents
symlink, resulting in infinite recursion. Detect this scenario and fix
it before merging user directories.
The upcoming NVIDIA 470 driver series will introduce a DLL (nvngx.dll)
for the support of NVIDIA DLSS in Proton. This change adds logic for
discovering the location of DLL files provided by the NVIDIA driver, and
copies them to C:\Windows\System32\

Add https://github.com/jp7677/dxvk-nvapi as a submodule. dxvk-nvapi will
not be copied into Proton prefixes by default, but instead will be
controlled via the environment variable PROTON_ENABLE_NVAPI. This is
done to avoid any potential adverse effects of the nvapi DLL existing
in cases where an application may require a function that is not
implemented by dxvk-nvapi.
This new functionality can be enabled by setting the following environment
variable to a value of `1`:
`PROTON_ENABLE_NVAPI`
This functionality is needed in order to support DLSS within Proton.

Initializing OpenVR with the app's game ID seems to cause problems with
Steam VR runtime stability when the game uses OpenXR. The negative
impact is that if OpenVR is started the initialization will be delayed
for 2 seconds by vrserver waiting for valid appid. But the wait goes
in parallel with main application startup and should not delay things
much, if at all.
Linux SteamVR doesn't seem to support the Linux XR_KHR_convert_timespec_time
yet but the games start to refuse to work without the extension even if
they do not actually use it.

Configure will also test the container engine by trying to run the
selected SDK image.
This may make the first configure a bit slow, as it downloads the image,
but after that the SDK will be cached locally.
Debian-like distributions install AFDKO's executables into libexec and
provide an `afdko` helper to call them.
Python's pip installs the executables in bin.
Let's support both.
