Add local calendar core integration brand icon

[allenporter]

Proposed change

Add local calendar brand icon using a material icon, similar to local calendar. Added the calendar-multiple variant since it seemed more fitting for an integration that supports multiple calendars.

Type of change

• [X] Add a new logo or icon for a new core integration
• [ ] Add a missing icon or logo for an existing core integration
• [ ] Add a new logo or icon for a custom integration (custom component)
  • [ ] I've opened up a PR for my custom integration on the Home Assistant Python wheels repository
• [ ] Replace an existing icon or logo with a higher quality version
• [ ] Removing an icon or logo

It looks like this includes changes from #1899 and a pull request for rtsptowebrtc that was never actually made.

Ah, whoops, fixed. (The rtsptowebrtc one was renamed rtsp_to_webrtc also merged earlier too).
