WindowCovering: fix Limits checks + factorization (project-chip#13729)

* DEV: Remove IsOpen IsClosed function and use CheckLimitState * DEV: Move HasFeature function for external usage * DEV: Factorize conversion function * DEV: Add IsPercent100thsValid check method * DEV: Add OperationalStatusSet Global field helpers function - automatically set global field * DEV: Add ComputeOperationalState function * Restyled by clang-format * DEV: Rename limits using "Over" to "Post" * DEV: Cleanup HasFeature function * DEV: Add comments to explain the convert function * DEV: Replace Limit Post by Past * Style: correct bad description of ConvertValue Co-authored-by: Restyled.io <commits@restyled.io>
