license: allow CDLA-Permissive-2.0 (#35939)

## Summary
- Add `CDLA-Permissive-2.0` to the accepted license lists in
`about.toml` and `deny.toml`
- Pre-requisite for the crypto migration to rustls/aws-lc-rs, which
introduces dependencies licensed under this permissive license

## Test plan
- [ ] `cargo deny check licenses` passes
