vkCreateInstance fails with VK_ERROR_EXTENSION_NOT_PRESENT due to lack of VK_KHR_wayland_surface extension support on Ubuntu 22.04

Description

When trying to use qrenderdoc on Ubuntu 22.04.1, my app fails at vkCreateInstance with VK_ERROR_EXTENSION_NOT_PRESENT. I eventually ran the issue down to requesting VK_KHR_wayland_surface.

App runs fine when launched from terminal command line but fails when launched from qrenderdoc.

This is unsurprising as Wayland is not listed as one of the compile-time supported windowing systems. However, Wayland is becoming the default on more OS's and I had to take specific steps to disable it before being able to launch the app.

I'm really not sure what should be done to resolve this but felt it should be noted for other people who might bump into this.

Steps to reproduce

Launch an app requesting VK_KHR_wayland_surface under qrenderdoc and note it fails.

Environment

• RenderDoc version: ./renderdoccmd --version
  renderdoccmd x64 v1.21 built from 98a9340
  APIs supported at compile-time: Vulkan, GL, GLES.
  Windowing systems supported at compile-time: xlib, XCB, Vulkan KHR_display.

• Operating System: uname -srvmpio
  Linux 5.15.0-46-generic #49-Ubuntu SMP Thu Aug 4 18:03:25 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

• Graphics API: Mesa Intel® UHD Graphics 620 (WHL GT2)

Thanks.

Wayland is not supported, see #853 . Your application should enumerate available instance extensions before trying to enable any.
