[CK] More lifetime-warning suppression ## Motivation The staging compiler picked up another change from upstream that leads to more lifetime-analysis warnings. This breaks the build, given CK is built with -Werror. As a result, compiler promotion is blocked. ## Technical Details This patch adds the pragma push diagnostics to ignore the lifetime-warnings in the modified files to unblock compiler promotion. ## Test Plan <!-- Explain any relevant testing done to verify this PR. --> ## Test Result <!-- Briefly summarize test outcomes. --> ## Submission Checklist - [ ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
