Subject: [PATCH] [IMP] web: Adds dynamicProps to Widget

As with fields, dynamicProps will be accessible to widgets from extractProps.
This commit will make readonly accessible as the first dynamicProps.
We'll be able to add more when we need them.

DynamicInfo.readonly is true iff the expression given as readonly
attrs in the arch is evaluated to true with the current record.
