Update Skia build for Vulkan headers (#55143)

Skia has its own set of Vulkan headers which Skia Vulkan sources expect
to be compiled against. This internal set of Vulkan headers should not
be seen by any users. Instead, users provide their own set of Vulkan
headers and Skia's public Vk headers will use the user's Vulkan headers
when included in user sources. Unfortunately, this has not been well
enforced and Skia is making changes to ensure that Skia's set of Vulkan
headers does not leak. This change updates Flutter's build of Skia to be
compatible with these Skia changes.
