This diff reimplements the virtual package logic to use a virtual filesystem layer instead of a hard. This has many advantages:
One disadvantage is that it further abstracts the file access logic, making it more difficult for tools written in third-party languages to interop with our installs (I have Flow in mind). That said, given that these tools already have similar issues with our installs (because of the zip layer) and have a relatively low usage, it might be acceptable for now.
Note that this doesn't cause any issue with TypeScript, because TypeScript is implemented in JavaScript and thus transparently benefits from our FS layer.
