Upgrade cbindgen and use unsafe(no_mangle) attributes (#8539)

Browse source 
To be compatible with the 2024 edition, we need to wrap the
`no_mangle` attribute in `unsafe()`.

The parsing for that in cbindgen was only added in the version 0.28,
but we couldn't upgrade cbindgen before because of a regression in
cbindgen 0.27 that prevented us from upgrading.
Now that cbindgen 0.29 is released with a fix, we can prepare for the
2024 edition
