Provide reflection hints for native compilation

[javier-godoy]

Add-on require some reflection hints for native compilation. It also requires -H:+AddAllCharsets

1. Add resource-config.json, reflect-config.json and ForeignRegistrationFeature.java

2. Run apt-get update && apt-get install -y fontconfig libfreetype6 fonts-dejavu

3. Compile with -H:+ForeignAPISupport -H:+AddAllCharsets --features=com.flowingcode.ForeignRegistrationFeature

4. Run the application with -Djava.home=something (as a workaround for https://mail.openjdk.org/pipermail/client-libs-dev/2022-December/009431.html)

However, it keeps failing with the following error, with seems to be a limitation of the native image:

Maybe this is related with the autosizing feature, we could disable it for the demos.
