MemPostings: keep a map of label values slices (#15426) 
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.
