fix: pass migrate and normalize flags to the CDK if set on the manifest (#15961)

## What
EDIT: Changing this PR to only set the normalize flag for now, since we want to hold off on the `migrate` flag until we are ready to ship this to all users

We need to provide the way to communicate the `Form-Based UI` <> `CDK` to be able to toggle the `normalization` and the `migration` for the given manifest. 
After the `Form-Based UI` is released to the world and stable - these flags should be removed or set to True at the CDK level for the time being.

## How
## Airbyte-Webapp
- set the `__should_normalize` and `__should_migrate` flags by UI to the `manifest` level

## Connector Builder Server
- handle the additional flags set by UI to be at the `root` of the requestBody == `config`, to not to introduce `declarative_component_schema.yaml` changes and handle this only in platform.
- This code path handles the above: `oss/airbyte-connector-builder-server/src/main/java/io/airbyte/connector_builder/requester/AirbyteCdkRequesterImpl.java` > `adaptConfig` for `ResolveManifest`.

## Can this PR be safely reverted and rolled back?
- [X] YES 💚
- [ ] NO ❌
