Table init exprs appear to be unimplemented #5628
Description
I would like to use tables of non-nullable values but Binaryen does not appear to support them.
Relatedly, the binary format parser does not appear to support init value expressions for tables.
I would note that there would appear to be some confusion about the encoding; in WebAssembly/function-references@3eea656, not part of a PR, the encoding becomes 0x40 0x00 tabletype expr, whereas V8 does not yet expect the 0x00 intermediate byte (and it's not in https://docs.google.com/document/d/1DklC3qVuOdLHSXB5UXghM_syCh-4cMinQ50ICiXnK3Q/edit#heading=h.3i2qhyi67r2d).

optimise wasm module with binaryen

I've partially implemented this (enough to satisfy my own needs) in pufferfish101007@26fa2e2; this was my first time using C++ so it's probably not very good, but if I happen to finish it off (by patching the text-format parser and adding tests), I can open a pull request here.

Sadly, use nullable table types
