Update vulkan-deps and Dawn

https://chromium.googlesource.com/vulkan-deps/+log/ba840d111dc5..16939fbb2bf7
https://dawn.googlesource.com/dawn/+log/270c044100ca..865c3f8e94e4

vulkan-deps rolls were stopped because, via
https://chromium.googlesource.com/vulkan-deps/+/f8fbc1af1572,
https://github.com/KhronosGroup/Vulkan-Loader/commit/d1db6c5bce9e caused
abort calls. This is fixed, via
https://chromium.googlesource.com/vulkan-deps/+/7ead01a90b31, in
https://github.com/KhronosGroup/Vulkan-Loader/commit/da810336e761.

The vulkan-deps update range includes, via
https://chromium.googlesource.com/vulkan-deps/+/feb59519331e,
https://github.com/KhronosGroup/SPIRV-Tools/commit/d35a78db57e6. That
change switches some internal uses of the SpvOp unscoped enum to the
spv::Op scoped enum. This requires Dawn
https://dawn.googlesource.com/dawn/+/eb949c87ee5a, which also switches
to the spv::Op scoped enum.

The Dawn range also includes
https://dawn.googlesource.com/dawn/+/0a7364815ce9 and
https://dawn.googlesource.com/dawn/+/865c3f8e94e4, necessary to suppress
test failures in webgpu_cts_tests on dawn-win10-x86-deps-rel. See
https://crbug.com/tint/1753 and https://crbug.com/tint/1755.
