feat: produce a no-dependencies shaded Mutiny jar

[jponge]

Ref: #1577

[jponge]

This shades and relocates JCTools and Smallrye Common Annotations. The JCTools .atomic. queue variants are removed as well as counters and maps.

On the sizes front the benefit isn't spectacular:

864K	implementation/target/mutiny-999-SNAPSHOT.jar
8.0K	/Users/jponge/.m2/repository/io/smallrye/common/smallrye-common-annotation/2.4.0/smallrye-common-annotation-2.4.0.jar
408K	/Users/jponge/.m2/repository/org/jctools/jctools-core/4.0.3/jctools-core-4.0.3.jar

1.1M	no-deps/target/mutiny-no-deps-999-SNAPSHOT.jar

[jponge]

I did a more agressive pruning:

972K	no-deps/target/mutiny-no-deps-999-SNAPSHOT.jar

The best we can do.

So basically, we are taking 100K... Not great. However, the result is still less than the sum of the two jars.

I'm merging this, but this won't be much advertised. Consuming the main mutiny artefact should be the norm, the shaded variant is to be used only if you know what you are doing.
