  Expose Tail Kind Call to MLIR (#98080)

I would like to mark a call op in LLVM dialect as Musttail. The calling
convention attribute only exposes Tail, not Musttail. I noticed that the
CallInst of LLVM has an additional field to specify the flavor of tail
call kind. I bubbled this up to the LLVM dialect by adding another
attribute that maps to LLVM::CallInst::TailCallKind.
