Canvas Performance: getRemixExportsOfModule calls createExecutionScope a lot

[balazsbajorics]

Looking at the Canvas render graph of resizing a PromiseCard:

7-8ms is spent inside the UtopiaRemixRootComponent, most of it seems to be multiple repeated calls to createExecutionScope !!

None of that code should run during a canvas interaction. Ideally none of that code should run when the user did not navigate or changed the routes available.
