A Discord user reported that StackWalker gives blank stacktraces.
MSVC's C++23 support is unstable, so we can't use std::stacktrace yet.
In the meantime, we can just return an empty string and remove the
unmaintained StackWalker library and its hacky upstream_utils script.
Many LED strips use different color order (GRB in particular is common).
This makes the change at the HAL level. This solves 2 problems; first, no code needs to change in the high level drivers, which was challenging for C++, and second, simulation will behave properly as no conversion is needed. The HAL will accept an array of data objects in the same order no matter what the selected output order is, and will convert before sending it to the FPGA for output.
To accomplish this, NEON bulk load/interleave instructions are utilized. The low level implementation (load, store, and alignment functions) come from the Simd Library. The high level implementations are inspired by the image conversion functions in the simd library, but have diverged significantly.
Much of the implementation uses templates and inlined functions rather than runtime parameters; This is a trade off between the size of the generated code and the amount of function calls done at runtime. Currently, the entire conversion operation is inlined.
* Use explicit this capture required by C++20
* Use C++20 span
* Replace wpi::numbers with std::numbers
* Fix C++20 clang-tidy warning false positive in fmt
* Remove ciso646 include since C++20 removed that header
* Fix global-buffer-overflow asan warnings in ntcore tests
* Add DIOSetProxy constructor to HAL
* Upgrade MSVC compiler to 2022
* Bump native-utils to 2023.2.7 (changes to std=c++20)

Use ghc::filesystem as fill on older GCC (e.g. RoboRIO).
This can be removed once all GCC platforms have upgraded to 8.1 or later.
File open functionality has been retained from LLVM but moved to "fs" namespace
and tweaked for improved consistency with std::filesystem (e.g. error_code is
passed by reference instead of returned).
Also update WPILibC's Filesystem functions to return std::string.

The field image and robot image can be loaded or just a wireframe used.
The robot can be moved and rotated with a mouse click + drag.
The robot position is settable in robot code via the Field2d class.
This imports Eigen 3.3.7, which will be used by the wpilibc implementation of
state-space control and mecanum/swerve forward kinematics (the forward
kinematics requires least-squares solutions via a matrix pseudoinverse).
While Eigen has parts licensed under BSD, MINPACK, and MPL2, the files we need
are only MPL2.
Imported from https://github.com/akrzemi1/Optional with minor changes:
- Compiler conditional simplifications (we only use recent versions)
- Move from std::experimental to wpi namespace
- Change tests to integrate with Google Test
Update LLVM use cases.
