[PM-3756] Disable node integration and enable context isolation in desktop (#6975)

* Disable node integration and enable context isolation

* Review comments

* Log in renderer through IPC

* Missed imports

* Mock electron API

* resourcesPath is undefined in the preload, but process.windowsStore works correctly

* Replace fromBufferToUtf8 conditional implementation for the `buffer` package

The current non-node implementation is different than the node implementation,
as the non-node would break when the contents can't be parsed as a URI component.
Replacing the impl by the `buffer` package makes the result match in both environments.

* Fix lint

* Add some more tests

* Remove buffer from devDependencies
