[Compiler] Addressing new compiler warnings (#3640)

Browse Source 
* [Compiler] Addressing new compiler warnings

Clang enables new lifetime warnings in production and we see build
errors due to this with the staging compiler.

The attributes added in this PR are suggested by the compiler. However,
I'm not very familiar with the code base, so the changes may be
incorrect.

* Update some more instances

* Adds file-level ignores via clang diagnostic pragma

The number of instances was large, so I decided to use file-level scope
to disable the warning via pragma clang diagnostic ignored.

It also showed this warning coming from the gtest dependency. For that,
I did add the respective command line flag to the CMake variables. I
don't know if this is acceptable or not.

* This adds the remaining instances

For a build on gfx90a.

* fix clang format

* Adding couple more instances from gfx1200 build

* Fixed another few instances
