[issue32901] Update 3.7 and 3.8 Windows and macOS installer builds to tcl/tk 8.6.8

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

Is "this will only be useful on Windows," in the source-deps readme still true? It appears that the tcl/tk tar.gz source is meant for Mac also.  (IE, has Xcode project files.)

Looking ahead, there is an 8.7a1 release.  I am hoping that 8.7 will be available for our 3.8, as it should include a rewritten Text widget that, among other things, will fix the slow long lines problem.  Do we wait for 8.7 final or do we start testing and, if necessary, adapting _tkinter and tkinter with, say, their .b1?
