This is a reland of 0b091e9bd3
Some blink web tests have been temporarily disabled to allow landing
changes to the JS API in V8.
Original change's description:
> [wasm][eh] Rename Exception to Tag in the JS API
>
> See:
> https://github.com/WebAssembly/exception-handling/issues/159
>
> This change only does the rename where it's observable. This should also
> be renamed throughout the codebase for consistency and will be done
> separately.
