:wave: Hey,

As a precursor to adding table support to the interpreter this PR adds support for tables to the runtest environment.

This allows run tests to request memory for tables and for it to be provided via vmctx.

This is a behaviour change from what we had before.

We used to put the start and end pointers. However it looks like that's not whats expected by the bound mechanism for heaps.

This changes it to pass the size in bytes of the heap.

This is wrong according to docs/ir.md.

Table bounds should be the number of elements and not the number of bytes.

However nothing works when I change it to that. Probably something to investigate further.
