Subject: [PATCH] vk_sync.h: include <wchar.h> for wchar_t type

vk_sync.h uses wchar_t in function pointer types (import_win32_handle,
export_win32_handle, set_win32_export_params) but does not include
<wchar.h>. Under glibc, wchar_t is transitively pulled in via
<vulkan/vulkan_core.h>. Under relibc, it is not, so mesa 24.0 fails
to compile vk_sync.c, vk_sync_binary.c, vk_sync_dummy.c with:

  src/vulkan/runtime/vk_sync.h:285:42: error: unknown type name wchar_t

Add an explicit <wchar.h> include so the type is always available
regardless of the transitive header chain.
