chore(devex): hogvm into common folder

[mariusandra]

Problem

We want to move the scattered library projects in the posthog monorepo into a common/ folder.

Changes

Second step. Moving over:

• Plugin transpiler
• HogVM (this PR)
• HogQL parser

The nr of changed files might be daunting, but it's mostly just tests and snapshots for the HogVM

How did you test this code?

CI tests pass. I don't expect any problems here since:

• All TS projects (frontend and plugin-server) use the HogVM from npm and are unaffected.
• The python HogVM is not used anywhere, and the changes to a few import paths where quite clear
