* upgrade default docker to rocm7.0.1
* turn on build and test on gfx950 by default
* use rocm-dev instead of rocm
* link libhiprtc for codegen targets
* resolving codegen compilation errors: removed calls to other std functions, resolved issues with int32_t: needed the correct header, put use of e8m0 into header guards
