Right now there's a bunch of code in VM and JSLock for the super legacy
shared VM for C API. This patch removes most of that code and hides
the last remnents of the single shared VM in `JSGlobalContextCreate`.

This shouldn't be a semantic change only a code cleanup. The only
places we looked at the VMType was to see if it was an API VM or
Web VM.

Lastly, VMType is now an enum class.
