    Modified Files:
    src/Directory.Build.props
    Log Message:
    Compile MSVC projects with /MP, 4 compiler processes per project

    Every project under src/ now compiles its source files in parallel (MultiProcessorCompilation), with CL_MPCount defaulting to 4 when nothing
    else sets it. A clean Release rebuild of sbbs3.sln on a 24-thread machine:

    no /MP 183s
    CL_MPCount=2 111s
    CL_MPCount=4 84s

    The cap is low because the GitLab runner overlaps several of these builds
    on one machine. Override from the command line with e.g.
    "build.bat /p:CL_MPCount=8"; the Visual Studio IDE sets CL_MPCount itself.
