[PATCH v2 2/2] winevulkan: Implement vk_icdGetPhysicalDeviceProcAddr.

[Georg Lehmann]

When using the windows vulkan loader vk_icdGetPhysicalDeviceProcAddr
is used for unknown physical device functions.
Fixes Red Dead Redemption 2 with vkd3d-proton. The game replaces wine's
vulkan-1.dll with a windows version that doesn't know functions used by
vkd3d-proton.
