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.

Opening file in append mode sets the offset to the end of the file prior
to each write. This allows user to append tags/notes to the log file
just before interesting events, e.g.:
local $ ssh ivyl@test
test $ echo "!!! FOCUS CHANGE" >> ~/steam-XYZ.log
The log file is deleted just before we open it anyway, so there won't be
any leftover content from previous session.
The DLL ships with the games and having the built-in version in
system32/syswow64 has unexpected consequences.
If the game is launched from a subdirectory, but the DLL is in current
working directory, the built-in takes precedence as CWD has lower search
priority than system directories (with the default SafeDllSearchMode).
By not installing amd_ags_x64.dll in system32/syswow64 the built-in is
still picked up correctly from lib/ when necessary.
There's an accompanying patch for wine that makes sure wineboot won't
install the dll, but since we construct our default_pfx in a special way
we also need to make sure that files won't get copied/linked there.
To make prefix updates smooth this change also removes any stale
amd_ags_x64.dlls that may have been installed by previous version of
Proton.
