fix(gnovm): Make GnoVM slice allocations before go runtime allocations

[deelawn]

This is to fix the first issue mentioned in #2738.

In short, when allocating and reallocating slices' underlying arrays, the VM was building the TypedValue slice before making the necessary VM allocations. It is important the VM allocations be done before the TypedValue allocations to ensure the values being allocated won't exceed the VM's limit. In extreme cases, unchecked allocations resulted in the VM hanging as it tried to allocate massive TypedValue slices in the go runtime.
