Bug/support installing minimal libcuvs c

[robertmaynard]

What this PR changes:

• Introduces a new CMake install component called cuvs_c
  • Which only install the C headers, libcuvs.so and libcuvs_c.so, and CMake logic to support find_package(cuvs_c)
  • This builds a firewall that allows downstream consumers to not require RAFT/RMM/etc
• Moves around the C headers to a separate directory to allow for easier install of just our C API
• Updates all the C API enums to have explicit values for every type
• Removes cutlass export dependency as it isn't needed

Still Working On:

• Refactor C API source file locations
• Rust build logic updated
• Java build logic updated
• Go build logic updated

What still needs to be discussed:

• If we want to restore find_package(cuvs COMPONENTS c_api)
• If we should a single C API header that includes ever other C API header. This would make binding logic easier
