fix(eks): overly permissive trust policies (#25473)

The *CreationRole* and the *default MastersRole* use the account root principal in their trust policy, which is overly permissive. Instead, use the specific lambda handler roles that need it, and remove the default masters role.

BREAKING CHANGE: A masters role is no longer provisioned by default. Use the `mastersRole` property to explicitly pass a role that needs cluster access. In addition, the creation role no longer allows any identity (with the appropriate `sts:AssumeRole` permissions) to assume it.
