Every callback registration allocated two empty CString buffers for its
handle name and full name. Keep unnamed callback, iterator and constant
handles without owned names and return the shared empty C string for those
properties. Named scopes and signals retain their owned strings.

Extend existing public API regressions to check empty callback and iterator
names alongside the named hierarchy. Validation: all 68 VPI unit/API tests,
all 10 ignored cocotb integrations, all-target clippy with warnings denied,
and workspace formatting.
