Update testsuite (#2054)

As well as the testsuite update there are two notable changes that
come with it here.  These can both be split out an landed first if
it makes sense.

1. wasm2c now supports element sections containing externref.  Currently
   only the null reference is supported.

2. element segments no longer use funcref as the default element type
   but instead, unless explicitly included in the binary, the
   element type defaults to the type of the table in which the segment
   is active.

Fixes: #1612 #2022
