The C info code has already been committed but this commit wires it into main.
Also remove the info Perl code and tests since they are no longer called.
After a stanza-upgrade backups for the old cluster are displayed until they expire. Cluster info was output newest to oldest which meant after an upgrade the most recent backup would no longer be output last.
Update the text output ordering so the most recent backup is always output last.

Many options that were set per test can instead be inferred from the types, i.e. container, c, expect, and individual.
Also finish renaming Perl unit tests with the -perl suffix.
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.
The existing static files would not work with 32-bit or big-endian systems so create functions to generate these files dynamically rather than creating a bunch of new static files.
Modified the info command (both text and JSON output) to display the archive ID and minimum/maximum WAL currently present in the archive for the current and prior, if any, database cluster version.
