vulkan: Use separate release semaphores for external textures

Chromium's ExternalVkImageBacking does not expect multiple different
external textures to be sharing the same release semaphore. This causes
freezes with
https://webgpu.github.io/webgpu-samples/samples/videoUploading on Linux
and other cases where multiple shared images are involved. Fix this by
creating a separate semaphore for each external texture being released.
