Provide "reflection usage hints" for native compilation in vaadin-quarkus-extension

[mstahv]

vaadin-quarkus-extension could help compilation of native binaries by providing hints built into the extension. Quarkus has handy helpers for that, but maintaining that for the whole Vaadin, including all components, is likely to be rather nasty work.

We could try to find a way to at least semi-automatically generate that or provide it as an unsupported feature so that community who does native compilation could contribute the missing pieces.
