feat: Copy ACES input transform from timeline clip to new media item

This commit adds functionality to copy the ACES input transform from a timeline clip to a new media item. It retrieves the IDT (Input Device Transform) property from the timeline clip and sets it on the new media item.

Also, it updates the ClipLoader class in plugin.py to read trimming information from the timeline item instead of using "Start" and "End" properties. The start time is calculated as the left offset of the timeline item, and the end time is calculated by adding the duration of the timeline item to its start time.

These changes improve compatibility and ensure accurate copying of clips in Ayon Core Resolve API.
