Martin Erhart 8037deb7af [mlir][memref] Add pass to expand realloc operations, simplify lowering to LLVM ...

There are two motivations for this change:
1. It considerably simplifies adding support for the realloc operation to the
   new buffer deallocation pass by lowering the realloc such that no
   deallocation operation is inserted and the deallocation pass itself can
   insert that dealloc
2. The lowering is expressed on a higher level and thus easier to understand,
   and the lowerings of the memref operations it is composed of don't have to
   be duplicated in the MemRefToLLVM lowering (also see discussion in
   https://reviews.llvm.org/D133424)
