feat: inspect and inject transient fields on serialization

[mcollovati]

Description

During serialization, classes are inspected for transient field referencing injectable components. The information is serialized along with the current session attributes, and retrieved during deserialization to inject instances again into the transient fields.

Class inspection can be restricted to filtering by package name, setting 'vaadin.serialization.include-packages' and 'vaadin.serialization.exclude-packages'.

Fixes #26
