Drop toposort and migrate to graphlib

[ravi-kumar-pilla]

Description

This ticket aims at dropping toposort dependency in favor of built-in graphlib if possible. Following how Kedro team did this - kedro-org/kedro#3728

Context

We were depending on Kedro's environment for toposort dependency and since Kedro dropped this dependency, Viz started failing. This also raises an issue of having transitive dependencies. We can improve the code base to remove such transitive dependencies in future - #1821

Possible Implementation

We use from toposort import CircularDependencyError, toposort_flatten in our layers module. We need to find an alternate implementation to toposort_flatten within graphlib to resolve this issue

Possible Alternatives
