Be able to filter what objects detected in birdsye view

**Describe what you are trying to accomplish and why in non technical terms**
I want to be able to prevent cameras from showing up in birdseye view unless specific objects (person, car, etc) are detected.

**Describe the solution you'd like**
Allow object filters for birdseye view

**Describe alternatives you've considered**
None

**Additional context**
When it gets windy and there is lots of movement in the frames, frigate is falsing camera displays on the birdseye window.

No files, tests, or entry points are named in the issue. Start by locating the birdseye view implementation and its object-detection data flow, then trace how cameras are selected for display. Done means cameras are hidden from birdseye view unless configured object types are detected, with coverage for the filtering behavior.
