Currently it was leading to an error if I tried to build it with a root user on a Linux environment. So in the end the type generation was just skipped:
```
22:51:55.757 $ node install-from-github.js
22:51:55.813 Building playwright...

```
Maybe we should also exit the script with an error code if the protocol generation was not successful.
`protocol.d.ts` had to move to `protocol.ts` otherwise typescript refuses to include it in the out directory.
Removed the old d.ts generator. It will need to be rewritten anyway.
These new types include private stuff that they probably shouldn't, and are missing documentation. I'll follow up with a better d.ts generator later.
