Upgrade zerocopy to 0.7.5

This project was upgraded with external_updater.
Usage: tools/external_updater/updater.sh update rust/crates/zerocopy
For more info, check https://cs.android.com/android/platform/superproject/+/main:tools/external_updater/README.md

The crate now uses `assert_matches` in unit tests. That isn't imported
in AOSP, so I've disabled tests for now.
