script: Migrate wrapKey/unwrapKey operation to use new normalization (servo#39780)

Refactoring of the algorithm normalization in servo#39431 introduces a new
algorithm normalization procedure to replace the existing one, and we
continue the migration here.

In this patch:

- The `SubtleCrypto.wrapKey` and `SubtleCrypto.unwrapKey` method is
migrated from using existing `normalize_algorithm_for_key_wrap` function
to using the new `normalize_algorithm` function.
- `SubtleCrypto::wrap_key_aes_kw` and `SubtleCrypto::unwrap_key_aes_kw`
are moved to the sub-module `aes_operation`.
- The custom type `KeyWrapAlgorithm` used by
`normalize_algorithm_for_key_wrap` is also removed.
- The following algorithm that had been copied to `aes_operation`
sub-module are removed in this patch since they are no longer used.
  - `SubtleCrypto::encrypt_decrypt_aes_ctr`
  - `SubtleCrypto::encrypt_aes_gcm`
  - `SubtleCrypto::decrypt_aes_gcm`
  - `SubtleCrypto::export_aes_aes`

Testing: Refactoring. Existing WPT tests suffice.
Fixes: Part of servo#39368
