d043670d - [mlir][func] Replace `ValueDecomposer` with target materialization (#114192)

[mlir][func] Replace `ValueDecomposer` with target materialization (#114192) The `ValueDecomposer` in `DecomposeCallGraphTypes` was a workaround around missing 1:N support in the dialect conversion. Since #113032, the dialect conversion infrastructure supports 1:N type conversions and 1:N target materializations. The `ValueDecomposer` class is no longer needed. (However, target materializations must still be inserted manually, until we fully merge the 1:1 and 1:N drivers.) Note for LLVM integration: Register 1:N target materializations on the type converter instead of "decompose value conversions" on the `ValueDecomposer`.
