fix(libSceRazorCpu): add sceRazorCpuNamedSync export

Resolve the XCuZoBSVFG8 import required by Killzone Liberation by adding sceRazorCpuNamedSync as a no-op returning success when capture is inactive.

Extend the RazorCpu behavior test and document the NID source and unverified console signature and capture behavior.
