vkd3d and dxvk integration (#2823)

* Add d3d sources for linux builds

* Return NOT_IMPLEMENTED for shared handle support on Linux

* Enable DirectX api on Linux

* Do not report DX11 support without FXC

* Initial version of SynchAPI emulation

* Neaten dx library name handling

* Neaten and use posix-synchapi

* Add premake option for DirectX on Vulkan

* s/SLANG_ENABLE_VKD3D_PROTON/SLANG_ENABLE_VKD3D

* Skip failing tests on vkd3d

* Regenerate vs projects

* Silence unused var warning
