When ancient history is pruned, geth serves old block bodies and receipts
back from era files on disk. Until now that fallback only worked for .era1
files (pre-merge), so requests for post-merge blocks backed by .ere files
failed even though the data was present. This PR generalizes the era store
to open both formats.

This implements a backing store for chain history based on era1 files.
The new store is integrated with the freezer. Queries for blocks and receipts
below the current freezer tail are handled by the era store.
