LOG: [MLIR][CAPI] add C API typedef to fix downstream C API usage (#135380)

This PR is after #135253 and #134935 to fix the error reported by
https://github.com/llvm/llvm-project/pull/135253#issuecomment-2796077024.
This PR Adds typedef declarations for `MlirLinalgContractionDimensions`
and `MlirLinalgConvolutionDimensions` in the C API to ensure
compatibility with pure C code.

I confirm that this fix resolves the reported error based on my testing.
