Wasm: Use environment to translate reference types instructions and add support for multiple tables

This commit introduces environment functions to handle the translation of
reference type instructions, analogous to how bulk-memory was implemented.

Additionally, the bulk-memory instructions that operate on tables are extended
to support multiple table indices.
