[wasm] Adjust flags after changed implications

This is a cleanup to remove unneeded flags after these changes (in
https://crrev.com/c/1988548):
* --future does not imply --wasm-tier-up any more, and
* --wasm-tier-up does not imply --liftoff any more.

Instead, now
* --wasm-tier-up is enabled by default,
* --wasm-tier-up has no effect if --liftoff is not set, and
* --future implies --liftoff.
