In #17920 , we introduce the new TVM FFI system, after various evolutions
and refactoring, we are getting to a state that the ffi component is ready to
be isolated out. This marks a major milestone of our ffi refactoring.
Summary of the Change
- Now all ffi related components(including python binding) are isolated
under the ffi folder
- The ffi part is now moves into its own package minimal that contains the
core ABI hopefully we start to become stable over time
- We modernize the package using `scikit-build-core` and the package can
be readily installed via ```pip install ./ffi```
- An alpha version can also be tried via `pip install apache-tvm-ffi`
- TVM compiler and runtime will depend on the the new ffi module
- For extensions that only needs to expose certain functions, they can
directly depend on tvm-ffi only
- Dynamic libraries(such as libtvm) that build on top of tvm-ffi will not be
impacted by the python ABI or torch ABI, so wheels can be created independent
from python/torch version
We will continue to evolve tvm-ffi a bit, but it should be at a reasonable
stable state. The change would pave path for us to further modularize the
stable part of components that can eable broad interactions, while continuously
improving the compiler
