Using std::min() and/or std::max() in sources where windows.h has been
include fails with

    error C2589: '(': illegal token on right side of '::' [D:\a\ninja\ninja\build\libninja.vcxproj]
    error C2062: type 'unknown-type' unexpected [D:\a\ninja\ninja\build\libninja.vcxproj]
    error C2059: syntax error: ')' [D:\a\ninja\ninja\build\libninja.vcxproj]

Avoid this by defining NOMINMAX for windows builds, which causes the
windows.h header to skip defining those two macros.

cmake: disable min() and max() macros in windows.h

Add Emacs package attributes, “Keywords” and “URL”
