refactor: abstract/reuse react component detection logic

[mdevils]

Summary

This is a follow-up refactoring after discussion here: #6053 (comment)

What was done:

1. React component detection / info gathering logic was abstracted and shared at react::components mod.
2. JsExport::get_exported_items was improved to return proper values in all cases, not just in a few pre-selected ones.
3. noNestedComponentDefinitions and useComponentExportOnlyModules were simplified.
4. Some seemingly incorrect useComponentExportOnlyModules tests were removed.

Please take a look, @dyc3.

My next steps would be fixing these issues related to useHookAtTopLevel rule: #6110, #6093.
