Fix location and content location headers in Resteasy Reactive

When providing a location, the URI was being decoded, so the value was being altered from what users set.

Note that these changes are based on what Resteasy already does: https://github.com/resteasy/resteasy/blob/dadddfb699a875c44ba05c0abe176873acbd9aa2/resteasy-core/src/main/java/org/jboss/resteasy/specimpl/ResponseBuilderImpl.java#L187

Fix quarkusio#33419

(cherry picked from commit ced8b0a)
