[Parser][NFC] Filter out unused instructions in gen-s-parser.py (#6095)
The new wat parser parses block, if, loop, then, and else keywords directly
rather than depending on code generated from gen-s-parser.py. Filter these
keywords out in gen-s-parser.py when generating the new wat parser and delete
the stub functions that the removed generated code used to depend on.
