feat: Add option to conditionally disable site instance patches (#18396)

Browse source 
* chore: allow conditional disable of the site instance override patches at runtime

* feat: add app.allowRendererProcessReuse property to allow runtime disable of site instance overrides

spec: add tests for the new allowRendererProcessReuse property

feat: add console warnings / errors for loading non context-aware native modules
  * Only error if the patch is disabled
  * Warn all the time, this will ship in Electron 7
