Support `copy()` for `zipfile`

Feature or enhancement

Proposal:

Currently, copying an entry within a ZIP file is cumbersome due to the lack of support for simultaneous reading and writing. The implementer must either:

• Read the entire entry and write afterwards (which is memory-intensive and inefficient for large files), or
• Use a temporary file for buffered copying.

Both approaches are more complex and less performant, due to the need to decompress and recompress data.

It would be much more performant and friendly by implementing a copy() method, using the similar internal buffered copying technique introduced by #134627 with the internal _ZipRepacker.

This also opens the door to support an efficient move() operation, composed of copy(), remove(), and optionally repack().

Comece lendo a entrada do módulo zipfile e a abordagem interna _ZipRepacker introduzida pela issue #134627. A alteração deve permitir a cópia eficiente de uma entrada enquanto o arquivo está aberto para leitura e escrita, com o comportamento e os casos extremos estabelecidos antes da implementação. O PR vinculado gh-151825 indica que o trabalho já está em andamento.
