Make levels 1-based in pg_log_backend_memory_contexts()

Both pg_get_process_memory_contexts() and pg_backend_memory_contexts
have 1-based levels, whereas pg_log_backend_memory_contexts() was using
0-based levels.  Align these.

This results in slightly saner behavior from MemoryContextStatsDetail()
in regards to the max_level.  Previously it would stop at 1 level before
the maximum requested level rather than at that level.
