[CK] Fix/suppress clang lifetimebound warnings with staging compiler. (#6550)

Browse Source 
## Motivation

New changes from upstream llvm-project cause an avalanche of warnings in
CK. Gonna disable them by ignoring the
lifetime-safety-intra-tu-suggestions flag until a better permanent
solution is found.

## Technical Details

<!-- Explain the changes along with any relevant GitHub links. -->

## Test Plan

<!-- Explain any relevant testing done to verify this PR. -->

## Test Result

<!-- Briefly summarize test outcomes. -->
