[mlir][bufferization] Update linalg integration tests to lower ops created by bufferization-to-memref pass

This commit prepares the linalg integration tests to be run with the new
BufferDeallocation pass which requires the bufferization-to-memref pass
to be run afterwards.
The bufferization-to-memref pass may create ops of the SCF, Func, Arith,
and MemRef dialects. Currently, not all integration tests execute all the
conversion passes necessary to lower these dialects to LLVM.
