ScopeInfo should have a public constructor

[mkouba]

Otherwise it can't be used for custom scopes in a BeanConfigurator. We should also add some javadoc to instruct the users to use io.quarkus.arc.processor.BuiltinScope for built-in scopes.

Is it ok to add a public constructor as part of REST TCK fix?

[mkouba]

@kenfinnigan sure. Pls update the javadocs as well.

[kenfinnigan]

Which javadoc? the ScopeInfo or somewhere else?

[mkouba]

Yep, ScopeInfo.
