Fix two major synchronization issues in `wgpu_val::vulkan`:

- Properly order queue command buffer submissions. Due to Mesa bugs, two semaphores are required even though the Vulkan spec says that only one should be necessary.

- Properly manage surface texture acquisition and presentation:

    - Acquiring a surface texture can return while the presentation engine is still displaying the texture. Applications must wait for a semaphore to be signaled before using the acquired texture.

    - Presenting a surface texture requires a semaphore to ensure that drawing is complete before presentation occurs.

A recent change by rustc, now in 1.79-stable, makes empty str constants
point to the same location: 0x01. This is an optimization of sorts, not
stable behavior. Code must not rely on constants having stable addresses
nor should it pass &"" to APIs expecting CStrs or NULL addresses.
D3DCompile will segfault if you give it such a pointer, or worse:
read random garbage addresses!

Pass the NULL pointer to D3DCompile if wgpu lacks a decent CString.
