CMake: Remove additional debugging compiler flags

Browse source 
Our previous setup lead to two unintended consequences:

* Debug flags were included in both release and debug builds instead
of just debug builds
* Clang doesn't support -gX (where X is the level of debugging
optimization), but we checked for -Og support instead

This commit avoids both of these scenarios by removing the additional
flags altogether. Partial resolution to #11856.
