Update operations in Transform dialect extensions defined in the Affine,
GPU, MemRef and Tensor dialects to use the more generic
TransformHandleTypeInterface type constraint instead of hardcoding
PDL_Operation. See
https://discourse.llvm.org/t/rfc-type-system-for-the-transform-dialect/65702
for motivation.
Remove the dependency on PDLDialect from these extensions.
Update tests to use !transform.any_op instead of !pdl.operation.
