[robotpy] Mirror most other subprojects (#8208)

GitOrigin-RevId: ac60fd3cf4a24023184376687da28373d14b781a

This mirrors the robotpy files for the following projects:
- apriltag
- datalog
- hal
- ntcore
- romiVendordep
- wpilibc
- wpimath
- xrpVendordep

This excludes cscore and the halsim wrappers for at this time.

NOTE: This does not hook these projects up to the build system, just simply mirrors the files. The building will take place in a follow up PR to make it easier to review the changes necessary to build.
