Subject: [PATCH 0/4] nova-core Improve pin initializer code

This is a minor series to improve some of the pin initializer code to:

1. Reduce redundancy caused by Result<impl PinInit<T, Error>> return
values with pin_init_scope().

2. Relocate code that technically fits in the pin initializer into the
initializer itself.

While, thanks to pin_init_scope(), it is also possible to keep it as is,
moving appropriate code into the initializer has the advantage that it
structures the dependencies of fields naturally.

For instance, intermediate data that is only needed for a single field goes
into the initializer block of this field, making it obvious that it is not
needed by anything else.

On the other hand, intermediate data that is needed for multiple fields to
initialize remains above the initializer, naturally indicating that it is
needed my multiple fields.
