Issue #15968: Incorporated Tcl, Tk, and Tix builds into the Windows build

solution.

Currently, Tix is not built in Debug configuration.

This change also:
- simplifies some Tcl/Tk-related msbuild properties for _tkinter
- copies the Tcl and Tk DLLs into the build output directory, meaning
  they will always be available after a build without having to copy
  them manually or change PATH
- removes PCbuild/build_tkinter.py: the solution does the build without
  needing to invoke Python (so Tcl/Tk/Tix can be built in parallel with
  the rest of the build using the `/m` msbuild command line switch)
- removes an outdated README concerning building Tcl/Tk on AMD64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
-   nmake -f makefile.vc MACHINE=AMD64
-   nmake -f makefile.vc INSTALLDIR=..\..\tcltk install
-   cd ..\..
-   svn export http://svn.python.org/projects/external/tk8.4.12
-   cd tk8.4.12\win
-   cl nmakehlp.c /link bufferoverflowU.lib

-   nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12 INSTALLDIR=..\..\tcltk install
