(2) still needs fix in dense2sparse by skipping zeros

The alloc->insert/compress->load chain needs to be
properly represented with an SSA chain now in loops
and if statements to properly reflect the modifying
behavior (runtime support lib is forgiving on breaking
this, but the new codegen is not).

This differential replaces all uses of SparseTensorEncodingAttr::DimLevelType with DimLevelType. The next differential will break out a separate library for the DimLevelType enum, so that the Dialect code doesn't need to depend on the rest of the runtime

TranslateIndicesArray take an array of SSA value and convert them into another array of SSA values based on reassociation. Which makes it easier to be reused by `foreach` operator (as the indices array are given as an array of SSA values).

Previously, the SparseTensorUtils.cpp library contained a C++ core implementation, but hid it in an anonymous namespace and only exposed a C-API for accessing it. Now we are factoring out that C++ core into a standalone C++ library so that it can be used directly by downstream clients (per request of one such client). This refactoring has been decomposed into a stack of differentials in order to simplify the code review process, however the full stack of changes should be considered together.
* (this): Part 1: split one file into several
* D133830: Part 2: Reorder chunks within files
* D133831: Part 3: General code cleanup
* D133833: Part 4: Update documentation
This part aims to make no changes other than the 1:N file splitting, and things which are forced to accompany that change.

This changes a couple of places that used to `return failure();` to now use `llvm_unreachable()` instead. However, `Transforms/Sparsification.cpp` should be doing the necessary type checks to ensure that those cases are in fact unreachable.

This moves a bunch of helper functions from `Transforms/SparseTensorConversion.cpp` into `Transforms/CodegenUtils.{cpp,h}` so that they can be reused by `Transforms/Sparsification.cpp`, etc.
See also the dependent D115010 which cleans up some corner cases in this change.
