ruby: recursively clear namespaces before removing the exported types

If a type is defined within another type, this fixes clearing the exports.
Otherwise, the type-within-a-type would not be cleared as the the parent type is
removed first.
ruby: in export_to_ruby, make sure that we save the current export state on error

Otherwise, clear_exports will fail afterwards
doc: make the link to the Ruby bindings documentation more prominent
ruby,doc: document the dependency discovery methods on Type
ruby,doc: when possible, use yard to generate documentation
ruby: use RbConfig instead of Config in cmake code
