Paulo Lopes f5c0d2eb56 Add SVM metadata and minimal substitutions to build graalvm native image applications. (#8963)
Motivation:

GraalVM native images are a new way to deliver java applications. Netty is one of the most popular libraries however there are a few limitations that make it impossible to use with native images out of the box. Adding a few metadata (in specific modules will allow the compilation to success and produce working binaries)

Modification:

Added properties files in `META-INF` and substitutions classes (under `internal.svm`) will solve the compilation issues. The substitutions classes are not visible and do not have a public constructor so they are not visible to end users.

Result:

Fixes #8959

This fix is very conservative as it applies the minimum config required to build:

* pure netty servers
* vert.x applications
* grpc applications

The build is having trouble due to checkstyle which does not seem to be able to find the copyright notice on property files.
