shim: retry application-ID init with d4r's project identity

Browse Source 
NGX 617.14 rejects application-ID initialization on this path (Cyberpunk
2077: 0xBAD0000C, or SR unavailable with 0xBAD00004). Streamline's RR
plugin reads capabilities right after that first Init, so a failure
there hides RR for the session even though the game's later project-ID
Init works. When the app-ID NVSDK_NGX_CUDA_Init fails and the caller
gave no project identity, retry once with d4r's own project identity
(the diagnostics' default) so the first Init succeeds; log the retry as
D4R_NGX_IDENTITY_FALLBACK. Port of the windows-branch fix in
tools/windows/ngx_runtime_initialization.h.
