crypto: Implement encrypt/decrypt for AES-CBC + JWK support (#33795)

* Add support for raw importKey with AES-CBC

Signed-off-by: Daniel Adams <msub2official@gmail.com>

* Support JWK import/export, importKey for AES-CBC

Signed-off-by: Daniel Adams <msub2official@gmail.com>

* Implement encrypt/decrypt for AES-CBC

Signed-off-by: Daniel Adams <msub2official@gmail.com>

* Update expectations

Signed-off-by: Daniel Adams <msub2official@gmail.com>

* Update Cargo.lock

* Pass MutableHandleObject as arg instead of returning raw pointer

Signed-off-by: Daniel Adams <msub2official@gmail.com>

* Swap order of checks in generate_key_aes_cbc

- Fixes WPT tests that expect to error on algorithm first before usages
