Align the Table implementation limits with the JavaScript Embedding
limits defined in the specification (from MAX_UINT32 to 1e7).

Introduce a new helper (max_table_init_entries) that returns the
maximum number of Table entry at initialization. It takes into account
the maximum Table size, which can be passed by a flag.
