  [JSC] Combine FuncRefTable entries

Reviewed by Mark Lam.

This patch combines FuncRefTable entries into one so that we don't need to access two separate vectors
everytime we call an indirect function.
This patch also constant-fold table-size since this information can be known constant at wasm module level.
