Nicolas Vasilache c59465e120 [mlir][Transform] Add support for mapping to GPU warps and to linear ids ...

This revisions refactors the implementation of mapping to threads to additionally allow warps and linear ids to be specified.

`warp_dims` is currently specified along with `block_dims` as a transform attribute.

Linear ids on th other hand use the flattened block_dims to predicate on the first (linearized) k threads.
An additional GPULinearIdMappingAttr is added to the GPU dialect to allow specifying loops mapped to this new scheme.

Various implementation and transform op semantics cleanups are also applied.
