Add comments to dwarf2/abbrev-cache.h

This patch started when I noticed that the unordered_set include
wasn't needed in abbrev-cache.h.  (That was probably leftover from
some earlier implementation of the class.)  Then, I noticed that the
class itself was under-commented.  This patch fixes both issues.
