Copilot b43390a070 Fixes #4677 - Refactors DimAuto for less coupling and improves performance (#4678)
* Phase 5: Add IsFixed and RequiresTargetLayout categorization properties

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Further simplify DimAuto.Calculate using IsFixed property

* Refactor for-loops to foreach and clarify DimFill logic

Refactored multiple for-loops iterating over view lists to use foreach loops for improved readability and reduced boilerplate. Removed unused variables such as viewsNeedingLayout and index counters. Clarified DimFill handling by continuing early if the DimFill is not valid or lacks a To property, reducing nesting and improving intent. Made minor formatting and code style improvements for consistency.

* Refactor subview filtering and sizing logic

Refactored repeated LINQ queries for subview filtering into reusable helper methods (`GetViewsThatMatch`, `GetViewsThatHavePos<TPos>`, `GetViewsThatHaveDim<TDim>`), reducing duplication and improving readability. Moved max content size calculations for various subview types into new helper methods (`GetMaxSizePos<TPos>`, `GetMaxSizeDim<TDim>`). Updated main logic to use these helpers. Adornment thickness calculation now uses a switch expression. These changes improve modularity and maintainability.

* Refactor subview categorization for layout calculation

Refactored layout calculation to use a single-pass CategorizeSubViews method, grouping subviews by relevant Pos/Dim types into a new CategorizedViews struct. This replaces multiple helper methods and reduces redundant iterations. Updated main logic to use these categorized lists, and unified size calculation helpers to further reduce code duplication. Improves performance and maintainability by consolidating subview processing and removing obsolete methods.

* Revert perf POC commits and add missing overrides to Combine types
