[CI] Moved Sanitized Test from Debug to RelWithDebInfo

[AlexandreSinger]

I expect the sanitized test to be the tall pole for the speed of the CI due to its long run time on the testcases. After investigating with Vaughn, we realized that this test was using the debug build of VTR. This was likely making it much slower than it needed to be.

To improve the speed of this test, moved it to use the release build. We still want symbols to give good error messages.

Prior to this change, the sanitized run took 15 minutes (with the build taking a little under a minute).

After this change, the sanitized run takes around 6 minutes (with the build expected to take around 3 minutes).

Nice gains! I'm seeing an absurd amount of compiler warnings in the CI run for this PR, do you know what's the reason for those?

LGTM other than that.

Good eye! I did not notice that. I gave it a quick look and it seems to be coming from a "maybe uninitialized" warning. I am not concerned about it; however its good to be aware of.

I believe this is similar to the IPO warnings that we suppressed which get revealed when more optimizations are performed. Since we do not care about being warning clean for this build, I do not think any action is necessary. Thanks for pointing it out!
