windows-release/tcltk-build: Update to handle Tcl/Tk 9

[zware]

• tcltk-build: Remove Tix
• tcltk-build: Split {Tcl,Tk}SourceTag into version and prefix parameters

Apart from the CI failure, looks good to me. I guess they need some better cross-compiling support, but hopefully you can override a build variable to get it to use the Win32 build during the ARM64 one?

[zware]

Yep, looking into what else needs the override now.

[zooba]

Another trick we could use here is to extract the version number from the header file, that way we can go back to setting just the tags when building:

$ver = @{}
Get-Content .\generic\tcl.h | ?{ $_ -match '#\s*define\s+TCL_([A-Z]+)_VERSION\s+(\d+).*'} | %{ $ver[$Matches[1]] = $Matches[2] }
$ver.MAJOR
$ver.MINOR

That doesn't help people trying to build separately (without this script), but the current change doesn't help them either.

[zware]

Hmm, could we actually do that in tcltk.props? I'm not too concerned about this solution being just for our purposes; once we do the update, the values in tcltk.props/tcl.vcxproj/tk.vcxproj will be right (for anyone sticking to the same version as us).

I think this is ready to go, but I'd rather someone else hit the big green button in this repo :)

Not so easily without adding more build-time dependencies (such as shelling out to Powershell or Python to do the command and print each variable one at a time - parsing stuff in MSBuild is a pain). It would be easier to use more wildcards and fewer hard-coded assumptions about the Tcl and Tk builds' outputs.

Have you been able to run test builds of it directly from this branch? It's possible, and I assume you've got the permissions, but if that's been fine then it's fine by me.

[zware]

Yes; see test build (unsigned), python/cpython#149477 for CI against it (using my fork of cpython-bin-deps).

[zooba]

Done. I'm off for the night now though, so if you start a signed build immediately you'll have to hope Hugo is about to approve it, or I'll do it tomorrow.

Thanks!
