Add validations on the creation of bind groups with storage textures

This patch adds all the validations on the creation of bind groups with
read-only and write-only storage textures.

1. Only the textures with STORAGE usage can be used as read-only or
   write-only storage textures.
2. The format of the texture view used as read-only or write-only
   storage texture must match the corresponding declarations in the
   bind group layout.
3. The texture view dimension of the texture view used as read-only or
   write-only storage texture must match the corresponding declaration
   in the bind group layout.

Note that we don't test the match of the sample count because currently
we don't support sample count > 1 when creating a texture with STORAGE
usage and creating a bind group layout with read-only or write-only
storage textrue binding type.

This patch also adds a unit test to verify that it is invalid to create
a bind group layout with either read-only or write-only storage texture
binding type and dynamic offsets.

This patch also implements the bind group with storage textures on
Vulkan to make the Vulkan fuzzer happy with this patch.
