Allow for work stealing when only holding read locks - #4012

This allows tasks with only read locks to be stolen by threads that are currently holding only read locks. The new compatibility check would also support write locks but `NodeTreeWalker` forces children of tasks with write locks to be executed on the same thread and thus no work is being stolen.

There was a problem hiding this comment.
The implementation looks good. Only some test suggestions and style bikeshedding left.
