Node Conformance Test: Refactor node e2e framework

For #30122, #30174.
Based on #30348.

**Please only review the last 3 commits.**

This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30348, it removed unnecessary dependencies in the node e2e test framework, because we've statically linked these dependencies.

The PR refactored the node e2e framework. Moving different utilities into different packages under `pkg/`.

We need to do this because:
1) Files like e2e_remote.go and e2e_build.go should only be used by runner, but they were compiled into the test suite because they were placed in the same package. The worst thing is that it will introduce some never used flags in the test suite binary.
2) Make the directory structure more clear. Only test should be placed in `test/e2e_node`, other utilities should be placed in different packages in `pkg/`.
