fix(servicecatalogappregistry): applicationName can not be changed after deployment (#24409)

Background:
* Customers wish to control or modify the stack id of the Application stack to follow their project conventions within CDK.
* In previous [fix](#24171), we had deprecated the stack id to push users towards using stack name as the main mechanism for stack identification.
* Default stack name as per this [fix](#24171) has `Application Name` embedded in it. If customers wants to **update the application name**, then a new stack name as well as new stack id will be generated, which will eventually create a new Application in a new stack.

Problem:
* Application associator associates all stacks in scope to an application.
* With `ApplicationName` in stack name, we will create an application within a stack. When customers attempt to update the name of the application, we will create a new stack and eventually create a new application, which is the first problem.
* In this new application within the new stack, we will try to associate all stacks within the `app` scope, which is already associated to the original application in the original stack and hence cannot be further associated to the new application which will make the deployment of the stack with updated name fail.

Fix:
* We will continue to honor customer provided stack Name.
* If no stack name is provided, then we will default it to `ApplicationAssociator-${hashValues(scope.node.addr)}-Stack`, which doesnt contain `Application Name`.
