fix: win_psDscAdapter targeted module cache refreshes

[haodeon]

PR Summary

Fixes #745 by ensuring a full Get-DscResource refresh is triggered when $env:PSModulePath changes.

Also reorders the cache staleness checks to prioritize detecting PSModulePath differences before evaluating stale resource entries.

Fixes #807 by ensuring a full cache refresh is triggered when cache is cold. It now builds a list $namedModules which determines whether targeted module refresh occurs, using this list if it does.

PR Context

When $env:PSModulePath changes, the cache may be rebuilt incorrectly if $Module remains set. The module environment may have changed outside the scope defined by $Module, but the refresh will only consider the provided modules.

When a module is deleted, the stale entries check will detect the change and initiate a cache refresh, skipping the check for stale paths. If the removed module is not in $Module, the stale entries get captured in $existingDscResourceCacheEntries and remain in the refreshed cache.

A change in PSModulePath should result in a full cache refresh and take priority over stale resource entries.
