* [wasm] return a WasmResult from `declare_table_elements` This method in particular needs to accommodate failure because any table index other than zero is currently invalid. * [wasm] additional failure handling improvements - Adds `WasmResult<()>` as the return type for most of the `ModuleEnvironment` methods that previously returned nothing. - Replaces some panics with `WasmError::Unsupported` now that the methods can return a result. - Adds a `wasm_unsupported!()` macro for early returns with a formatted unsupported message.
