Andreas Kling 43ff2ea8d8 LibJS: Use regular stack for VM call frames instead of Vector storage
Keeping the VM call frames in a Vector could cause them to move around
underneath us due to Vector resizing. Avoid this issue by allocating
CallFrame objects on the stack and having the VM simply keep a list
of pointers to each CallFrame, instead of the CallFrames themselves.

Fixes #3830.
Fixes #3951.
