Update Rust crate uniffi to v0.25.0 (#303)

## Type of change
```
- [ ] Bug fix
- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other
```

## Objective
Updated Uniffi to 0.25.0. This required some code changes:
- BitwardenError now needs to implement Error.
- Defining the uniffi_support types in both crates seems to be causing
duplicate symbols on xcode at least, so we instead use
`ffi_converter_forward!` to forward the type definitions from the
`bitwarden` crate to the `bitwarden-uniffi` crate.
- There is a name collision with our `Send`, and Rust's `Send`, so I've
changed the imports to use `vault::Send`.
- Removed the unused UDL file.
