feat: Namespaced IPC

[timfish]

• Closes Namespace Sentry Electron IPC #1231

You can set the IPC namespace in the main process:

import * as Sentry from '@sentry/electron/main';

Sentry.init({
  dsn: '__DSN__',
  ipcNamespace: 'some-app',
});

And the renderers:

import * as Sentry from '@sentry/electron/renderer';

Sentry.init({
  ipcNamespace: 'some-app',
});

And for the preload:

import { hookupIpc } from '@sentry/electron/preload-namespaced';

hookupIpc('some-app');
