[PATCH i-g-t v2 36/39] lib/chamelium/v3: Implement hot plug toggle scheduling method

[Louis Chauvet]

This commit adds a new method to the Chameleon V3 wrapper to schedule hot
plug detect (HPD) toggle events. This feature is useful for testing
suspend and resume behaviors, as it allows the simulation of device
connection and disconnection events at specified times.
