Description
The Programmatic Dependent Launch (PDL) mechanism allows for a dependent secondary kernel to launch before the primary kernel it depends on in the same CUDA stream has finished executing. Available starting with devices of compute capability 9.0, this technique can provide performance benefits when the secondary kernel can complete significant work that does not depend on the results of the primary kernel.
Cuco kernels should all support PDL.

Research direction
Start by reviewing the CUDA Programmatic Dependent Launch documentation linked in the issue, then inventory the cuco kernels and their launch paths. Determine the changes and validation needed for each kernel to support PDL on compute capability 9.0 and newer; the work is done when all cuco kernels support the mechanism.
