GH-49511: Fix rare doctest Table.join_asof and default_memory_pool failures
(#50446)
### Rationale for this change
#49511 : `Table.join_asof` outputs a non-deterministic number of chunks, so
the printed table sometimes appears as one chunk and sometimes as several
(rarely).
`default_memory_pool` prints `bytes_allocated=0` except when a preceding
(failing) doctest allocated from the process-global pool (also rarely).
### What changes are included in this PR?
Addition of `.combine_chunks()` to `Table.join_asof` (and removal of two
trailing spaces) in `table.pxi`
Change to `bytes_allocated=...` from `bytes_allocated=0` in `memory.pxi`
### Are these changes tested?
Yes, local doctest tests OK.
### Are there any user-facing changes?
No, just docstring changes.
