On the last discussion about bindings we agreed expression are always
bound to single prop and cannot be reused.
Here added new prop.type = 'expression' as a replacement to
dataSource.type = 'expression'.
This will let us unify expression/variable reference and avoid deep
dependencies. Expressions and actions become similar.
For now both expression prop and legacy expression data source are
supported until we migrate completely in db.

Here improved copy/paste behavior.
Before variables outside of copied tree were inlined. For example
ErrorMessage were loosing its expression when duplicated within same
form.
Now expressions and variables are preserved
and variables are inlined into expressions when paste target do not have
such variable. For example ErrorMessage get `"initial" == "error"`. With
upcoming UI it will be more obvious. The main idea here to not loose all
expressions but only references to unavailable variables.
Here added action copy paste support.
When all action dependencies are scoped to copied instance new variable
nams are ussed.
When some any dependency is not scoped execution is removed from copied
prop.

Here changed behavior when copy and paste without changing instance
selection. Now it works as duplicating and copy is inserted after
selection.
Added cmd+d and ctrl+d shortcut to do this with single press without
polluting clipboard.
Here fixed the case when copy pasted form looses state and give errors
on submit.
Immerhin now converted to esm to work in tests.
Added tests for instances copy paste plugin.
The new logic is copy data sources as is if they are bound to copied
instances.
The new computeExpressionsDependencies used to detect if expression
depends on data sources outside of copied instances scope.
