Implement get_property_ref for Layouts in the interpreter
...
We can fetch the Property<> references from the custom_properties hash
by using the property name that was changed in the moving declarations
pass.

Get rid of visible x/y properties in GridLayout
...
It doesn't really make sense to have them in the API, the grid layout is
supposed to "own" the surrounding space. That can be an element and then
it should be a (0, 0) and distribute the element's width/height, or in
the future it can be a cell of a grid layout. Then there's an (x/y), but
that's implicit / hidden.

Prepare for "virtualizing" the grid layout's width/height
...
Instead of storing the "within" element that we unconditionally take the
"width" and "height" properties from, let's pass through a property
reference expression to the width/height to use. For now that's still
the layout parent's width/height, but with this it can be replaced in
the future to refer to a "virtual" property that belongs to parent cell.

Fix handling of properties of nested optimized layout elements
...
We need to traverse also into the expressions of nested layouts to ensure
any references inside are updated as the
"virtual" properties are moved.

Allow for the positioning of PathLayouts via x/y properties

These are just "virtual" properties that will be transformed into
property members of the main struct through the optimized elements
sub-pass.

This works, but it's still missing support for positioning of the layout
itself.
