LibJS+LibWeb: Defer initialization of the Agent after VM constructor

Browse source 
This helps unwind a niggly depedency where the VM owns and constructs
the Heap and the Agent. But the agent wants to have customized
construction that depends on the heap. Solve this by defering
the initialization of the Agent to after we have constructed the
VM and the heap.
