Make Maven signing conditional via property

Gate calls to signAllPublications() behind a project property so signing only occurs when explicitly enabled. The release workflow now exports ORG_GRADLE_PROJECT_signMavenPackages=true for relevant jobs, and build scripts were updated to check the property before signing (core, java libraries: dxf, io, net, pdf, serial, svg). The preprocessor signing check was also adjusted to look for the signing.signMavenPackages property. This lets CI enable signing when keys are available and avoids signing failures when signing credentials are not configured.
