Clean up/refactor the batch scripts used for building on Windows.

This is mostly a backport of issue #21907, but also includes a few
extras necessary to make the bulidbot scripts as thin as possible.

Tools/buildbot/README.tcltk-AMD64

-Comments on building tcl/tk for AMD64 with the MS SDK compiler
-==============================================================
-
-I did have to build tcl/tk manually.
-
-First, I had to build the nmakehlp.exe helper utility manually by executing
-   cl nmakehlp.c /link bufferoverflowU.lib
-in both the tcl8.4.12\win and tk8.4.12\win directories.
-
-Second, the AMD64 compiler refuses to compile the file
-tcl8.4.12\generic\tclExecute.c because it insists on using intrinsics
-for the 'ceil' and 'floor' functions:
-
-  ..\generic\tclExecute.c(394) : error C2099: initializer is not a constant
-  ..\generic\tclExecute.c(398) : error C2099: initializer is not a constant
-
-I did comment out these lines; an alternative would have been to use
-the /Oi- compiler flag to disable the intrinsic functions.
-The commands then used were these:
-
-   svn export http://svn.python.org/projects/external/tcl8.4.12
-   cd tcl8.4.12\win
-   REM
-   echo patch the tcl8.4.12\generic\tclExecute.c file
-   pause 
-   REM
-   cl nmakehlp.c /link bufferoverflowU.lib
