Tig a7209bcd88 Improves robustness of Dim, Pos, and SetRelativeLayout (#3077)
* Updated overview docs

* Updated toc

* Updated docs more

* Updated yml via dependabot

* Initial work in progress

* Fixed some autosize things

* Revamped Pos / Dim API docs

* Removed margin

* horiz->width

* Updated MessageBoxes and Dialogs Scenarios to use AutoSize

* AutoSize->Auxo

* Adds validation

* prep for Dialog to use Dim.Auto - Simplify unit tests to not depend on things not important to the unit test (like Dialog)

* prep for Dialog to use Dim.Auto - Simplify unit tests

* prep for Dialog to use Dim.Auto - Simplify unit tests

* prep for Dialog to use Dim.Auto - Make Dialog tests not depend on MessageBox

* Started on DimAuto unit tests

* started impl on min/max.

* started impl on min/max.

* Added DimAutoStyle

* Added arg checking for not implemented features

* Temporarily made DimAutoStyle.Subviews default

* Removed unneeded override of Anchor

* Fixed GethashCode warning

* Implemented DimAuto(min)

* Fixed unit tests

* renamed scenario

* WIP

* Moved ViewLayout.cs into Layout folder

* Clean up cocde formatting

* Renamed and moved SetFrameToFitText

* Fixed API docs for SetRelativeLayout

* Factored out SetRelativeLayout tests

* Better documented existing SetRelativeLayout behavior + unit tess

* Debugging Pos.Center + x in SetRelativeLayout - WIP

* Progress on low level unit tess

* Initial commit

* Restored unmodified scenarios

* Bump deps
