This updates to the 2027-1 toolchains. This also is the first version
with the `rules_bzlmodrio_toolchains -> wpilib_toolchains` rename, so
the surface area of the change is a little bit big.
The opencv dep has bzlmod'ified as part of this as well.
This adds shortcuts for static only, shared only, and binary projects.
The end result is that it is pretty easy from here to publish all the
arifacts needed.
