/**
* idl_test_shadowrealm is a promise_test wrapper that handles the fetching of the IDL, and
* running the code in a `ShadowRealm`, avoiding repetitive boilerplate.
*
* @param {String[]} srcs Spec name(s) for source idl files (fetched from
* /interfaces/{name}.idl).
* @param {String[]} deps Spec name(s) for dependency idl files (fetched
* from /interfaces/{name}.idl). Order is important - dependencies from
* each source will only be included if they're already know to be a
* dependency (i.e. have already been seen).
