PJ Reiniger 32cd2ddf8e [upstream_utils] Remove patch that results in building with NDEBUG causing ODR issues (#8539)
Semiwrap / meson / robotpy define `NDEBUG` when building their software
in all modes, while `allwplib` only does it when building debug. This
causes the size of `DenseMap` to differ between the shared libraries
built here, and the extension modules built in `mostrobotpy`, causing
segfaults when you try to execute code that uses `DenseMap`. This is not
a problem with the robotpy code in `allwpilib`, because bazel uses the
exact same compiler flags when building the shared libraries and
pybind11 extensions.
