Updated versions and fixed build errors. See comments.

- This commit fixes the regular build and the glium example. The WGPU
  example needs an updated imgui-wgpu to point to the new imgui-sys
  version for things to work.
- The im_str and ImString usage deprecations are not fixed yet.
- There is no version bump for cimplot yet.
