This PR improves in-place send/receive capabilities for SparseMatrixCSC types within our MPI communication utilities. It allows data to be directly written into pre-allocated buffers on the receiving end.
Key Changes:
InplaceSparseInfo Struct: A new struct, InplaceSparseInfo, has been added to encapsulate the metadata required for the in-place transfer of SparseMatrixCSC objects.
Performance and Memory Optimization: Enabling in-place transfers for SparseMatrixCSC significantly reduces overhead from serializing and deserializing sparse matrix data. This is particularly beneficial for large sparse matrix operations in distributed memory environments.
