Subject: [PATCH] Added video block creation by dropping (#8122)

* Added video block creation by dropping

Dropping a video file on an insertion point now creates a Video Block
instead of a File Block.

This was done by adding the corresponding transform for the Video Block
It supports immediate preview until upload.

* Added error handling
