Migrate Hilla modules to Platform

[manolo]

Remove from Hilla repo hilla-spring-boot-starter hilla-react-spring-boot-starter hilla-maven-plugin ?

Rename hilla to hilla-lit

Update vaadin-core including hilla-react (what todo with hilla-lit if they are incompatible ?) vaadin-spring-boot-starter including hilla-react-spring-boot-starter (what to do with the lit part ?) vaadin-maven-plugin must consider hilla-maven-plugin actions somehow? what about dev-server stuff?

User Migration Path

• Users of dev.hilla:hilla-react should migrate vaadin-maven-plugin and just com.vaadin:vaadin
• Users of dev.hilla:hilla should migrate to com.vaadin.hilla:hilla-lit (and vaadin-maven-plugin)
• Users of com.vaadin:vaadin should generally not migrate, and our aim is to include com.vaadin.hilla:hilla-react for them.
• Users of com.vaadin:vaadin that want to use hilla-lit they need to add com.vaadin.hilla:hilla-lit

Why not create ”hilla” instead of separate ”hilla-react” and ”hilla-lit”?
