chore: add pretest:e2e script to make the command build itself

[AllanZhengYP]

Description of changes:
Add a prehook to test:e2e command, to make sure all the command it needs already built when being executed. It makes test:e2e command more self-contain(by no requiring manually building the components before running it).
