Begin using new APIs between Go 1.17 and 1.19

[Jacalz]

Description:

This implements the following changes:

• Use the new safer and more convenient (as well as faster in the case of atomic.Pointer[]) atomic APIs in Go 1.19.
• Stop using execabs and revert back to os/exec again.
• Use the convenient strings.Cut() function instead of IndexByte and friends.
• Use math.MaxInt instead of math.MaxInt32.
• Update fredbi/uri to v1.1.0 for performance improvements.
• Update x/image to v0.14.0 for various improvements.
• Some dependencies are updated with newer go.mod versions for cleaned up go.sum file from more aggressive module graph pruning.
• Added a generic version of the unbound channels that can replace code generation in the future (requires Go 1.21 for clear()).
• The async queue no longer relies on the unsafe package.

For #3242

Checklist:

• Tests included.
• Lint and formatter run with no errors.

This PR became larger than what I was hoping for, partially because the GopherJS support removal PR took some time to get ready. Anyway, I think this should be quite simple to review either way. The changes aren't that huge and the commits can be looked at one by one if necessary.
