Update wgpu to 0.20

[hecrj]

This PR updates wgpu to 0.20. Depends on #2416.

Unfortunately, this wgpu update doesn't seem to work very well on my end (Arch, X11, RTX 4090, NVIDIA drivers). 0.19 is smooth as butter for me, while in 0.20 the examples feel very sluggish and I constantly get a validation error:

2024-05-01T14:25:29.145657Z ERROR wgpu_hal::vulkan::instance: VALIDATION [VUID-vkAcquireNextImageKHR-semaphore-01779 (0x5717e75b)]
        Validation Error: [ VUID-vkAcquireNextImageKHR-semaphore-01779 ] Object 0: handle = 0x4fac1c0000000032, type = VK_OBJECT_TYPE_SEMAPHORE; | MessageID = 0x5717e75b | vkAcquireNextImageKHR():  Semaphore must not have any pending operations. The Vulkan spec states: If semaphore is not VK_NULL_HANDLE it must not have any uncompleted signal or wait operations pending (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkAcquireNextImageKHR-semaphore-01779)

I imagine there is something wrong with the release, although maybe I missed something. Let me know if it works for you!

Works alright without validation errors and sluggish behavior on a Radeon RX 5600 XT but there is a lot more log output that there used to.

So I just tried the Tour example

 Linux: 6.9.7-1-default
 KDE: 6.1.1
 Graphics Card: Nvidia 3070 TI. Running the latest 555 driver(explicit sync go brr)

And the program is one of the smoothest on my pc. This was on Debug mode.

However, I am getting a bunch of validation warnings.

2024-07-03T11:04:54.914016Z  WARN wgpu_hal::vulkan::instance: VALIDATION [WARNING-vkGetDeviceProcAddr-device (0x22b1fbac)]
       Validation Warning: [ WARNING-vkGetDeviceProcAddr-device ] | MessageID = 0x22b1fbac | vkGetDeviceProcAddr(): pName is trying to grab vkGetPhysicalDevicePresentRectanglesKHR which is an instance level function   

Also tried Game Of life. It is pretty smooth.
