### Issue Details

* **Electron Version:**
  * 10.1.3
* **Operating System:**
  * win7 sp1 x64

- without worldSafeExecuteJavaScript, `(webFrame|webContents).executeJavaScript('new Promise(resolve => setTimeout(() => resolve(2), 3000));')` works as expected; the executeJavaScript promise waits for the eval promise.
- in the case of webFrame the evaled promise is returned raw
- in the case of webContents the promise is marshaled
- with worldSafeExecuteJavaScript, both error with: "An object could not be cloned"
- webContents should continue marshaling promises, otherwise its an unnecessary breaking change
- webFrame should marshal promises for consistency with webContents
- the clone restriction would be on the promise resolve value

### To Reproduce
`(webFrame|webContents).executeJavaScript('new Promise(resolve => setTimeout(() => resolve(2), 3000));')`
