It now uses SQP for problems without inequality constraints, which is
faster.

This reverts commit d1de7663d3.
Intellisense is still broken on Windows Athena target with the error
`incomplete type "Eigen::Matrix<double, 3, 3, 0, 3, 3>" is not allowed`.
The Google C++ protobuf implementation has issues with dynamic linkage across DLL boundaries because it uses global variables. It also has a compile-time dependency because the protoc version must exactly match the libprotobuf version. Using nanopb with a customized generator fixes both of these issues.

As string_view operations on std::map<std::string> won't be integrated
until C++26, placeholder implementations are used which are less efficient
in a couple of situations (e.g. insert with hint).
Previously, both wpi/expected and JSON's cpp_future.h would define enable_if_t and conjunction in wpi::detail, leading to conflicts if both were included in the same cpp source file. By renaming the namespace wpi/expected uses, there is no longer a conflict.
Group memory doxygen into one module.
Remove concept alias and add doxygen definitions for foonathan memory.
\concept was added as a doxygen command in 1.9.2 and is meant to be applied to concepts. Inserting them into standard comment paragraphs causes doxygen to interpret the following text as a concept name and add it to the documentation, as well as remove the text from the paragraph.
In the upstream repo, this alias links to markdown documentation, so it's not usable for us anyways.
That, plus adding the doxygen definitions/aliases from upstream cleans up most of the errors/weird output from doxygen for foonathan memory.
Reading exported data from shared objects on windows is broken. It requires __declspec(dllimport). However, this is problematic, as we use the same static libraries both from a shared and static context. So we can't just blindly apply dllimport.
The linker should have caught this, as data members are exported in a different way. However, due to a bug in native-utils, data member symbols were exposed directly. However, interacting with those data member was completely broken.
The only way we can really solve this is to just not use static data members. We're pretty good about this in WPILib itself. However, protobuf is absolutely terrible at this. There are a ton of inline functions that access global data. For the protobuf library itself, we can solve this easily enough.
However, for the generated protobuf code, this is much more problematic. The member needed to bypass the global data is private. This means using just the stock protobuf code, this problem is not solvable. But, protobuf generated code has insertion points. Those insertion points let us add our own code into the generated code via a protoc plugin. And it just so happens that an insertion point exists to add extra public methodsto the generated protobuf header. There is also an insertion point to let us add to the cpp file.
The methods we need are the getters, for unpacking protobufs. For any protobuf that has a message as a member, we generate a new wpi_x() getter (the existing one is just x(), where x is the field name). We then implement this in the cpp file. A trick we can use is in the cpp file, we can safely call the x() function, as the cpp file is in the same library as the global. Thus we can call that inline method, and not actually need to directly access any internal private state of the protobuf object.
TL;DR, all protobuf classes that have messages as fields now have a wpi_x() accessor that must be used instead of x() if you want the code to work on windows. After wpilibsuite/native-utils#212, the bad code will fail to link, rather then just fail at runtime.
The new upstream_utils command-line API has been nice, but the
copy-upstream-to-thirdparty command has been annoying to type. Since it
already has documentation, we can shorten it to make it easier to
remember and type.
