cranelift-wasm: Pass ir::Tables into all the translate_table_* methods

This serves two purposes:

1. It ensures that we call `get_or_create_table` to ensure that the embedder
already had a chance to create the given table (although this is mostly
redundant due to validation).

2. It allows the embedder to easily get the `ir::TableData` associated with this
table, and more easily emit whatever inline JIT code to translate the table
instruction (rather than falling back to VM calls).
