  test: Add test for doing string interpolation of growing list value

String interpolation of lists allocates a lot of bits of memory and
requires care to track possible location changes across collect calls
in many places. Test this by doing string interpolation of a sequence
of lists.

  Log Message:
  -----------
  save/restore 'list' value during string interpolation

Each put_c or snek_poly_format call does allocation and may end up
performing a collect, which will move the 'list' value
around. Save/restore the list value across sequences of those
calls. Pull the 'size' value out of the list instead of fetching each
time, while *not* pulling the data value out as that only gets used in
one place and would need re-fetching anyways.
