Detailed Description

Algorithm to explicitly lock a set of decorations.

In some derivation configurations, multiple algorthims can be modifying the same decorations (for example TruthDressingTool). In such cases, we cannot lock the decorations at the end of the algorithm, as is usually done, since this would cause subsequent algorithms to fail. However, we also don't want to leave the decorations unlocked, as the fix for ATLASRECTS-8008 would cause those decorations to be lost in a deep copy. Instead, in those cases, we can use this algorithm to explicitly lock the decorations after all algorithms that modify it have completed.

Note, though, that such configurations are likely not compatible with MT.
