fix: self managed stackset dependencies

[cgeers]

adds an explicit dependency between MgmtAccEBRuleStackSet and associated self managed roles Even though there is an implicit dependency because of the use of Fn::GetAtt, we also need an explicit dependency to handle stack teardown gracefully. Adds cfn-lint exclusion

@cgeers As per cfn-lint the dependency is implicit. so do we need to add it manually?

We don't need to have our behavior dictated by default linting rules, and it's clear that with just the implicit dependency, the race still exists. Doing something seems better than doing nothing.

TBF though, I've not tested this enough to know if the explicit dependence is enough to properly trigger teardown order properly consistently, but it seems like a pretty reasonable course of action to me.
