tox.ini: Add environment local-conda

[mkoeppe]

This environment creates an isolated conda installation within the tox environment directory,
similar to local-homebrew.

To run:

   MAKE="make -j8" tox -e local-conda-forge-standard
   MAKE="make -j8" tox -e local-conda-forge-minimal

Depends on #29087

This is fixed in singular 4.1.2. Singular/Singular@80a9ffc

A workaround is to do export CPPFLAGS="$CPPFLAGS -UNDEBUG" in Singular build script.
