Enable Wasm BigInt. This enables WASM_BIGINT while maintaining (hypothetical) Safari 14 support
by shimming BigInt64Array and BigUint64Array if they are missing. I think the
last time we tried to enable WASM_BIGINT was before #2019 so our chances
are significantly better this time.

This will fix dynamic linking bugs, reduce code size, and improve speed.
