Fix some bugs with zipfile serialization (#32244)
Summary:
Stacked PRs
* #32958 - Make zip serialization the default
* **#32244 - Fix some bugs with zipfile serialization**
It includes the following changes:
* Split up tests so that we can test both serialization methods
* Loading something within a buffer doesn't work anymore, so those tests are only on the old serialization method (it's possible but introduces a big slowdown since it requires a linear scan of the entire zipfile to find the magic number at the end)
* Call `readinto` on a buffer if possible instead of `read` + a copy
* Disable CRC-32 checks on read (there was some issue where miniz said the CRC was wrong but `zipinfo` and `unzip` said the zip file was fine)
