all: Go 1.19 support

This adds early Go 1.19 support. There are a number of things that don't
work yet, but the smoke tests pass so it's at least working for a
significant subset of programs.

This change also switches from CircleCI convenience images to upstream
Go images. This makes it a bit easier to use the latest Go versions.
Also, the convenience images are not updated anymore.
