Omkar Kabde b8079cd294 GH-54637: [Python] add MemoryPool support to pq.read_table (#54919) ...

### Rationale for this change
`pq.read_table` has no way to pass a memory pool. `ParquetReader` and `Dataset.to_table` already accept one, it just wasn't added.

### What changes are included in this PR?
I added a `memory_pool` argument to `read_table`, `ParquetFile` and `ParquetDataset`. It is passed to `ParquetReader` and to `Dataset.to_table`, with docstrings updated.

### Are these changes tested?
Yes. I added new tests in `test_basic.py` - It reads a Parquet file with a tracked memory pool and check that the pool was actually used. They cover `read_table`, `ParquetFile` and `ParquetDataset`.

### Are there any user-facing changes?
New optional `memory_pool` keyword. No breaking changes.
