unpack-trees: preserve index extensions
Make git checkout (and other unpack_tree operations) preserve the untracked cache. This is valuable for two reasons: 1. Often, an unpack_tree operation will not touch large parts of the working tree, and thus most of the untracked cache will continue to be valid. 2. Even if the untracked cache were entirely invalidated by such an operation, the user has signaled their intention to have such a cache, and we don't want to throw it away.
