Log Message:
sbbs3: disable PDB generation for Release|Win32 builds

Adds src/sbbs3/Directory.Build.targets, auto-imported by MSBuild after
every sbbs3 .vcxproj's body, which overrides DebugInformationFormat to
None in ClCompile and GenerateDebugInformation to false in Link for the
Release|Win32 configuration across all 33 projects (including
scfg/scfg.vcxproj).

The motivation is sporadic, non-deterministic "internal compiler error"
failures observed on the Windows GitLab runner -- random source file
and line each run, persisting after AV exemption and single-instance
runner limiting. The root cause is mspdbsrv.exe (the shared PDB writer
spawned by cl.exe under /Zi) wedging or thrashing across the seven
sequential builds the windows-x86 [sbbs] job performs in one shot;
mspdbsrv outlives a single cl invocation and a single MSBuild process,
so per-runner throttling does not help. Eliminating the compiler /Zi
and linker /DEBUG settings removes mspdbsrv from the Release pipeline
entirely.

Verified by building ans2asc.vcxproj Release: produces a working .exe
(~42% smaller, no debug sections), no .pdb in either the output dir or
the intermediate dir, and MSBuild evaluates _DebugSymbolsProduced as
false. Debug builds are unaffected.

The CI artifact list in .gitlab-ci.yml never shipped .pdb files anyway.
