Remove [dz]gemmtr symbols from Windows build

[IsabelParedes]

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

The new patch removes the symbols zgemmtr and dgemmtr, and replaces the calls to these functions with the logic taken from version 4.4.3. This is only applicable to windows.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you, but it looks like there was nothing to do.

Instead of changing this file, we should remove cmplx.f and dlapack.f from Makefile.win as they are not needed when using an external blas library like we do.

Removing the files seemed to cause too many undefined symbols errors, and removing more seemed to have broken the build 🫤

I updated the patch again to make minimal changes while still removing these two symbols. It seems to be working now.

I'm not sure why the windows build is getting stuck

x86_64-w64-mingw32-gcc   -shared  -o ../../../modules/x64/internet.dll 
internet.o libcurl.o sockconn.o Rhttpd.o Rsock.o sock.o dllversion.o 
internet.def -L../../../bin/x64 -lR -lRgraphapp -lwininet -lws2_32 
-L""/lib/x64 -lcurl

Hi! This is the friendly automated conda-forge-linting service.

I failed to even lint the recipe, probably because of a conda-smithy bug 😢. This likely indicates a problem in your meta.yaml, though. To get a traceback to help figure out what's going on, install conda-smithy and run conda smithy recipe-lint --conda-forge . from the recipe directory. You can also examine the workflow logs for more detail.
