Work gracefully with downlevel NONBLOCKING_QUERY_RESOLVE

https://docs.rs/wgpu/latest/wgpu/struct.DownlevelFlags.html#associatedconstant.NONBLOCKING_QUERY_RESOLVE

As of writing it's only on Desktop GL < 4.2

Not exactly sure what we need to do here exactly, but at the very least it should be tried out and documented how to work with it!

only on Desktop GL < 4.2

I'm a bit curious about this since the wgpu docs only say 4.4+, is it that AMD_query_buffer_object could be available on 4.2?

[Wumpf]

oh interesting. I actually just blindly quoted what @cwfitzgerald wrote on wgpu chat 😄

Then it's probably 4.4 :)

Notably once gles gets support for timestamp queries, it will also have not have this downlevel feature
