* ci: Port some CI jobs to self-hosted runners

This PR ports the following CI jobs to use self-hosted runners:

- cannon-go-lint-and-test
- contracts-bedrock-build
- go-lint
- go-test-kurtosis
- go-e2e-test
- cannon-prestate

These jobs benefit from running on beefier hardware. Since Go cache data is shared among the executors, it also allowed me to remove a lot of the manual caching logic from our builds while  improving Go compilation times overall.

I'll provide a separate writeup detailing exactly how the executors work.

* use test result directories in the workspace
