Describe the enhancement requested

Now, C++ Parquet API already supports CRC in reading and write.

Though system like S3 will ensure the storage data works well. But some data storage like HDD or SSD might corrupt. And network might provide bad result. So having CRC would helps.

Now it's better to has crc in Python code.

Component(s)

Parquet, Python

@danepitkin @AlenkaF This seems useful to expose in Python indeed.

GH-37242: [Python][Parquet] Parquet Support write and validate Page C…
68ba49d 
…RC (#38360)

### Rationale for this change

The C++ Parquet API already supports enabling CRC checksum for read and write operations.

CRC checksum are optional and can detect data corruption due to, for example, file storage issues or [cosmic rays](https://en.wikipedia.org/wiki/Soft_error).

It would then be beneficial to expose this optional functionality to the Python API too.

This PR is based on a previous PR which became stale: #37439

### What changes are included in this PR?

The PyArrow interface is expanded to include a `page_checksum_enabled` flag.

### Are these changes tested?

[ ] NOT YET!

### Are there any user-facing changes?

The change is backward compatible. An additional, optional keyword argument is added to some interfaces.

Closes #37242
Supersedes #37439
* Closes: #37242
