Extend Visualize Frustum GUI plugin to support camera sensors

[iche033]

Visualize Frustum GUI plugin (#2707) adds frustum visualization for logical camera sensors by subscribing to the logical camera sensor's frustum topic, e.g. /logical_cam_sensor/frustum (gazebosim/gz-sensors#491). One improvement is to extend the plugin to support visualization of other types of camera sensors, starting with a regular RGB camera sensor.

Desired behavior

The GUI plugin allows users to select other camera topics for visualizing frustums

Alternatives considered

Another option for enabling/disabling frustum visualization is to parse the //sensor/visualize sdf tag

Implementation suggestion

In the topic drop down list, we can also support gz.msgs.CameraInfo msg type which is published by many other types of camera sensors. On callback, we should be able to compute camera frustum info (near, far, hfov, etc) from the intrinsic params.
