We added gc_deinit() and gc_never_free(), but I think they need work for split heap use.

Tentatively assigned to @tannewt as part of the split heap work.

Switch all ports to auto-growing split heap
8137e2d 
This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.

On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.

This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.

Fixes #8512. Fixes #7334.
