Attachment: Bug 1755389 - wasm: Add stack tracing support to WebAssembly.Exception. r?lth

This commit adds stack tracing support to WebAssembly.Exception
following the WebIDL snippet in the explainer [1].

JS::ExceptionStackOrNull is modified to propagate the stack
trace for a WasmExceptionObject in addition to ErrorObject.
This should make the rich stack display work in the devtools
console.
