Code handling repetitive boolean operations when using several objects from a Collection would not handle result mesh properly, re-creating for each object without properly freeing it. Further more, existing code was effectively converting the BMesh to mesh twice, including a modification of the initial (input) mesh, which modifiers should never do! Removed the extra useless conversion, which also gives a small improvement in performances: With as simple of a scene as four objects (three operands in a collection, and the modified one) totalling 20k vertices/faces, this commit: * Avoids 2MB memory leak per evaluation (!). * Speeds up boolean evaluation by 5-10%. Found while investigating some production files of the Project Heist here at the Blender Studio.
