core: Update Vulkan headers

[sargunv]

To support #4315, I updated the Vulkan-Headers submodule to the latest v1.4.x patch to get the official VK_OHOS_surface declarations.

This required dealing with some deprecations, as we were previously on v1.3.x. My understanding is this upgrade doesn't have significant runtime or compatibility implications on our other targets, but I'm not at all an expert here—please check me.

Coded with Codex CLI / GPT-5.5 as part of #4315; see that PR for AI usage details.
