feat: OAuth2 database field

[betodealmeida]

SUMMARY

More work on Snowflake OAuth2 (this PR depends on #30082). This PR introduces a new field for the database configuration modal, allowing OAuth2 client information to be provided by the user:

The component combines the 5 different input fields, and then passes them inside the masked_encrypted_extra attribute on database CRUD:

{
  "oauth2_client_info": {
    "id": "123456",
    "secret": "XXXXXXXXXXXX",
    "authorization_request_uri": "https://account.snowflakecomputing.com/oauth/authorize",
    "token_request_uri": "https://account.snowflakecomputing.com/oauth/token-request",
    "scope": "refresh_token session:role:USERADMIN"
  }
}

(Note that ideally we would pass these in the parameters field, and let the DB engine spec build the object in encrypted_extra. But the build_sqlalchemy_uri method — as the name suggests — only builds an URI, so we would have to modify it to return a tuple with (uri, connect_args) if we passed them client information inside parameters, and also figure out a way to inform that these fields should be stored in encrypted_extra, not extra, so for now the frontend does the work. I left a small TODO for me to fix this in the future.)
