gfx:Add callback to IPipelineCreationAPIDispatcher (#3556)

* gfx:Add callback to IPipelineCreationAPIDispatcher

Add the callback to IPipelineCreationAPIDispatcher in Vulkan backend
in slang-gfx lib.

* gfx:add uuid for vulkan pipeline dispatcher

Add a define of SLANG_UUID_IVulkanPipelineCreationAPIDispatcher
for Vulkan specific IPipelineCreationAPIDispatcher such that
libgfx.so can have special handle to Vulkan pipeline dispatcher without
break binary compatibility.

In the RendererBase::initialize call, we will provide this new UUID when
the DeviceType is Vulkan.

* gfx: add new variable to GfxGUID

Add new variable to GfxGUID IID_IVulkanPipelineCreationAPIDispatcher
with initialization of SLANG_UUID_IVulkanPipelineCreationAPIDispatcher
to make the implementation aligned with existing
GfxGUID::IID_IPipelineCreationAPIDispatcher.
