Blink needs %ErrorPrototype% in order to properly set up the inheritance
chain from DOMException, as specified in WebIDL:
https://heycam.github.io/webidl/#es-DOMException-specialness
This patch is similar to commit 5ec1cddcd ("Expose %IteratorPrototype% as an
intrinsic in the public API"), with the difference that there was no entry
for %ErrorPrototype% in any of the mappings in contexts.h.

Stream views can be used concurrently by multiple threads, but

This places in the scaffolding for completely relying on the embedder
for these APIs. Once Chrome uses these instead of the old APIs,
we can cleanup further by removing the old callback insertion points
and not exposing the streaming APIs if callbacks aren't provided.

TryHandleSignal was originally limited by conditional compilation to only
platforms where the WebAssembly trap handler is supported. This caused build
problems, because not all the macros we needed were defined everywhere.
Instead, we make TryHandleSignal available on all POSIX platforms, but it
unconditionally returns false if the trap handler is not supported.
