Andreas Haas 6b650574fc [wasm] Allow multi-table initialization in the wasm-module-builder
This CL just adds a parameter to addElementSegment and adjusts all
existing tests.

Note that addElementSegment contains some convenience code to construct
one initial table if it does not exist yet. I did not extend that code
to multiple tables. If you want to use multiple tables, you have to
create them first before calling addElementSegment.
