Using `clang-tidy`'s `modernize-use-default-member-init` check and manual review of the changes, and some extra manual changes that `clang-tidy` failed to do. Also went manually through all of `core` to find occurrences that `clang-tidy` couldn't handle, especially all initializations done in a constructor without using initializer lists.
