For two reasons:
1) Some apps will only enable or attempt to enable HDR if BitsPerColor is >= 10.
2) Encouraging apps to create 10-bit swapchains for use in hardware dithering on Gamescope/Steam Deck and to have more precision thru scanout color transforms
Disable stdcall aliasing and enable kill-at to ensure our exported
functions don't have the @8, @40, etc suffixes.
This still keeps `--enable-stdcall-fixup` as otherwise the linker can
get confused trying to find exports from the .def. This does not result
in aliases being added, just for them to be found to add to the export
table.
This also switches d3d11 to use the MinGW provided dxgi.lib for linking
and d3d10 to use the MinGW provided d3d11.lib for linking.
Unfortunately the .a's we output seem to still have the @blah that we
killed so we cannot use them for internal linkage since using kill-at.
Tested that what we get out of MinGW now is what we want with dllexp.

This trips up Stalker Anomaly for some reason, but initializing an output
is not meaningful anyway in this situation since we either know the output
in question already, or we don't and it cannot be in a non-default state.
Closes#3531.
If there are monitors on the system that are not associated with
any adapter, enumerate all monitors for all adatpers. May solve
some issues if device filter options are used on multi-GPU systems.
Death Stranding: Director's Cut crashes if HDR was last enabled in-game and CheckColorSpaceSupport reports support for HDR but it is not globally enabled in DXGIOutput::GetDesc1's ColorSpace.
It seems safer to just lock HDR behind an option to avoid any teething issues like this. It sucks, but it also makes sense in a way.
vkd3d-proton 2.8 released last year with support for the new swapchain
interface.
No need to keep support for this legacy interface hanging around when
it complicates adding DxgiOptions support to the swapchain.
Unreal Engine 4 titles use AGS/NVAPI to try and enable
HDR globally.
They can key this off IDXGIOutput::GetDesc1's ColorSpace
being HDR10.
Many of these UE4 games statically link against AGS.
This is a problem as when UE4 tries to enable HDR via AGS,
it does not check if AGSContext, and the display info etc
are nullptr unlike the rest of the code using AGS.
So we need to special-case UE4 titles to disable reporting a HDR
when they are in DX11 mode.
The simplest way to do this is to key off the fact that all
UE4 titles have an executable ending with "-Win64-Shipping".
We check if d3d12.dll is present, to determine what path in
UE4 we are on, as there are some games that ship both and support HDR.
(eg. The Dark Pictures: House of Ashes, 1281590)
Luckily for us, they only load d3d12.dll on the D3D12 render path
so we can key off that to force disable HDR only in D3D11.
Sometimes we can't get an EDID if things aren't plumbed fully, or some displays just have broken EDIDs.
This accounts for both of those cases by using some dummy data if we are missing information.
Fixes value reporting to match Windows on common displays such as LG OLEDs.
Adds the ability to punt the global colorspace into HDR from SetColorSpace1.
We have no way of checking the actual Windows colorspace as the
only public method for this *is* DXGI which we are re-implementing.
So we just pick our color space based on the DXVK_HDR env var
and the punting from SetColorSpace1.
We might expand on this in future, but this is good enough for an
initial implementation.
FEX would like clean symbols for experimenting with making thunks down the line.
We also just shouldn't be exporting a bunch of random crap -- sadly -fvisibility=hidden doesn't help with a bunch of stuff :(
For reference, RADV also does this.
