Instead of always materializing a new sparse tensor after reshape, this patch tries to fuses the reshape (currently only on COO) with GenericOp and coiterates with the reshaped tensors without allocating a new sparse tensor.

No need for a temp COO and sort even when converting dense -> CSC, we can instead rotate the loop to yield a ordered coordinates at beginning.

This change adds a new `SparseTensorType` class for making the "dim" vs "lvl" distinction more overt, and for abstracting over the differences between sparse-tensors and dense-tensors. In addition, this change also adds new type aliases `Dimension`, `Level`, and `FieldIndex` to make code more self-documenting.
Although the diff is very large, the majority of the changes are mechanical in nature (e.g., changing types to use the new aliases, updating variable names to match, etc). Along the way I also made many variables `const` when they could be; the majority of which required only adding the keyword. A few places had conditional definitions of these variables, requiring actual code changes; however, that was only done when the overall change was extremely local and easy to extract. All these changes are included in the current patch only because it would be too onerous to split them off into a separate patch.

The bulk of D142074 seems to have gotten overwritten due to some sort of merge conflict (afaict there's no record of it having been reverted intentionally). So this commit redoes those changes. In addition to the original changes, this commit also:
* moves the definition of `getRankedTensorType` (from `Transforms/CodegenUtils.h` to `IR/SparseTensor.h`), so that it can be used by `IR/SparseTensorDialect.cpp`.
* adds `getMemRefType` as another abbreviation.

This is part of an effort to migrate from llvm::Optional to
std::optional. This patch changes the way mlir-tblgen generates .inc
files, and modifies tests and documentation appropriately. It is a "no
compromises" patch, and doesn't leave the user with an unpleasant mix of
llvm::Optional and std::optional.
A non-trivial change has been made to ControlFlowInterfaces to split one
constructor into two, relating to a build failure on Windows.

When concat along dim 0, and all inputs/outputs are ordered with identity dimension ordering,
the concatenated coordinates will be yield in lexOrder, thus no need to sort.

Since STEA isa Attribute, and that's just (a wrapper around) a pointer, the extra `const` and `&` aren't necessary for function arguments.

The attribute tells the operator to handle symmetric structures for 2D tensors.
By default, the operator assumes the input tensor is not symmetric.
