GH-50037: [Python] test_table_uses_memory_pool flaky on macOS 14 job
(#50045)
### Rationale for this change
Fixes #50037
### What changes are included in this PR?
Add `gc.collect()` before `prior_allocation = pa.total_allocated_bytes()`
in `test_table_uses_memory_pool`
and also add to `_check_to_pandas_memory_unchanged` helper with the same
pattern.
Same fix as #44793
### Are these changes tested?
Not reproduced locally yet.
### Are there any user-facing changes?
No.
