[PATCH v2 0/2] Remove MSys Support

I am trying to learn more about the git code base and came across the issue where the support of MSys environment was to be dropped. This patch is my first contribution towards it.

The msysGit and the MSys v1.x has been dropped into this patch and the USE_NED_ALLOCATOR variable was duplicated here in the implementation so its deduplication was also made in this patch.

          mingw: remove msysGit/MSYS1 support
      
     -    The msysGit (i.e. Git for Windows 1.x' SDK) is no longer used and the
     -    last known user for MSys1 + MinGW has switched to MSys2. So there was no
     -    reason to keep the msysGit/MSys1 config section. This Patch intends to
     -    remove the support of both the builds and throw an error on
     -    execution.
     -
     -    The output of `uname -r` if returns us with '1.' then it relates with MSys1
     -    build environment and msysGit which we don't want to continue ahead and thus
     -    an error can be expected.
     -
     -    The MSYS2 is currently used into the MinGW so we can get that part
     -    running directly without any conditionals required.
     +    MSys has long fallen behind MSYS2 in features like Unicode or
     +    x86_64 support or even security bug fixes, and is therefore no
     +    longer used by anyone in the Git developer community. The Git for
     +    Windows project itself started switching from MSys to MSYS2 early
     +    in 2015, i.e. about eight years ago. Let's drop supporting MSys as
     +    a development platform.
