Issue:
When modifying EC2 image attribute to add organization ARN to launch permissions, moto silently ignores it.
**How to reproduce**

```
image = boto3.resource("ec2").Image(ami_id)
arn = "someOrganizationArn"
image.modify_attribute(
    Attribute="launchPermission",
    OperationType="add",
    OrganizationArns=[arn],
)

launch_permissions = image.describe_attribute(Attribute="launchPermission")["LaunchPermissions"]
assert launch_permissions == [{"OrganizationArn": arn}]
```

I expected that the organization arn that was added to the launch permission was visible afterwards via describe_attribute however it was not. Moto API calls are successful, but what happened was there, there was no launch permissions at all. Moto silently ignored adding an organization ARN to launch permission of an image.

Using boto3==1.21.9, botocore==1.24.46 and moto==5.0.0

Pull request description:
EC2: modify_image_attributes() now supports all LaunchPermissions
Fixes #7318 

`modify_image_attributes()` now supports the `LaunchPermission`, `OrganizationArns` and `OrganizationalUnitArns` attributes

Internally, the launch_permissions are now stored as a dict, more closely resembling the actual data.
