Split react-components into core and pro parts

[mshabarov]

Describe your motivation

Vaadin Core / open source users should be able to use core/free React components without Vaadin license.

Describe the solution you'd like

Acceptance Criteria:

• [x] React components are split into @vaadin/react-components (free) and @vaadin/react-components-pro (commercial) npm packages, this change is re-applied
• [x] Platform versions has react-components in core and react-components-pro in vaadin
• [x] Flow adds @vaadin/react-components-pro package into package.json in vaadin dependency is used in a project. @vaadin/react-components are added for both vaadin-core and vaadin.

Note: this is planned between 24.4 beta and GA, so that these changes don't block beta release and beta testing.

Describe alternatives you've considered

Created the React components split PR: https://github.com/vaadin/react-components/pull/242

Flow will pick/discard react components by the mode flag ("mode": "react") in the versions files and both vaadin-core-versions.json and vaadin-versions.json are always checked if available so for Flow there is nothing extra for step 3 to add.

Extended test to check this case explicitly: https://github.com/vaadin/flow/pull/19103

i have pushed a branch in platform with the necessary changes. let us wait after beta https://github.com/vaadin/platform/tree/react-component-pro

[mshabarov]

Done. Tested with having vaadin and vaadin-core. Vaadin adds react-components-pro in the first case and does not in the second case.
