9921ef73c8 [mlir][sparse] remove singleton dimension level type (for now) 
Although we have plans to support this, and many other, dimension level type(s), currently the tag is not supported. It will be easy to add this back once support is added.

NOTE: based on discussion in https://discourse.llvm.org/t/overcoming-sparsification-limitation-on-level-types/62585

bcfa7baec8 [mlir][CAPI] Add CAPI bindings for the sparse_tensor dialect. 
* Adds dialect registration, hand coded 'encoding' attribute and test.
* An MLIR CAPI tablegen backend for attributes does not exist, and this is a relatively complicated case. I opted to hand code it in a canonical way for now, which will provide a reasonable blueprint for building out the tablegen version in the future.
* Also added a (local) CMake function for declaring new CAPI tests, since it was getting repetitive/buggy.
