Feature: automatic camera resolution configuration (#6810)

* Add auto configuration for height, width and fps in detect role

* Add auto-configuration for detect width, height, and fps for input roles with detect in the CameraConfig class in config.py

* Refactor code to retrieve video properties from input stream in CameraConfig class and add optional parameter to retrieve video duration in get_video_properties function

* format

* Set default detect dimensions to 1280x720 and update DetectConfig to use the defaults

* Revert "Set default detect dimensions to 1280x720 and update DetectConfig to use the defaults"

This reverts commit a1aed0414d.

* Add default detect dimensions if autoconfiguration failed and log a warning message

* fix warn message spelling on frigate/config.py

* Ensure detect height and width are not None before using them in camera configuration

* docs: initial commit

* rename streamInfo to stream_info

* Apply suggestions from code review

* Update docs

* handle case then get_video_properties returns 0x0 dimension

* Set detect resolution based on stream properties if available, else apply default values

* Update FrigateConfig to set default values for stream_info if resolution detection fails

* Update camera detection dimensions based on stream information if available

These input args tell ffmpeg to read the mp4 file in an infinite loop. You can use any valid ffmpeg input here.
