While investigating lock contention on `MemPostings`, we saw that lots of locking is happening in `LabelValues` and `PostingsForLabelsMatching`, both copying the label values slices while holding the mutex. This adds an extra map that holds an append-only label values slice for each one of the label names. Since the slice is append-only, it can be copied without holding the mutex.
