[rocm-libraries] ROCm/rocm-libraries#6147 (commit 8035856)

[CK] Replace daily CI builds with mainline compiler with TheRock compiler. (#6147)

## Motivation

Since the compiler team has deprecated the amd-mainline branch and
switched to TheRock, we'll start building a docker image with TheRock
artifacts and building/testing Ck with that.
