[NFC] Internally rename `ArrayInit` to `ArrayNewFixed` (#5526)

To match the standard instruction name, rename the expression class without
changing any parsing or printing behavior. A follow-on PR will take care of the
functional side of this change while keeping support for parsing the old name.

This change will allow `ArrayInit` to be used as the expression class for the
upcoming `array.init_data` and `array.init_elem` instructions.
