Needed for Red Dead Redemption 2 under vkd3d-proton.
RDR2 requires us to use the native Vulkan loader, and vkd3d-proton recently enabled VK_KHR_fragment_shading_rate which exposes physical device procs unknown to the loader.
Previously, when we queried vkGetPhysicalDeviceFragmentShadingRatesKHR via. vkGetInstanceProcAddr, the native loader tried to call vk_icdGetPhysicalDeviceProcAddr from the WineVulkan ICD to resolve this, which didn't exist causing the loader to nullptr itself and crash.
This commit implements the vk_icdGetPhysicalDeviceProcAddr export, required for ICD version 4, via. forwarding to wine_vkGetInstanceProcAddr and fixes that problem.

We should still support getting it via vk_icdGetInstanceProcAddr.

This is not correct. vk_icdGetPhysicalDeviceProcAddr should only return function pointers for physical device level functions. This returns function pointers for *all* functions, so the loader will treat every unknown function as a physical device function. [1]
The proper way to do this is by generating a new dispatch table similar to vk_instance_dispatch_table in vulkan_thunks.c with only functions that take a physical device as the first argument.
