Trilinos: minimize E4S CUDA build (#28591)

* trilinos: update dependencies

Use the tribits deps to clarify some dependencies, and group some together
using `with` statements, eliminating some transitive conflict duplication.

* trilinos: Restricit cuda incompatibility

* e4s: vastly reduce number of packages in trilinos-cuda build

Not clear who the customers of cuda-enabled trilinos are, or what options
they need, or which sets of options conflict...

* e4s: remove ~wrapper from trilinos+cuda
