Subject: [PATCH] Revert "build: cmake: use -O0 for debug build"

This reverts commit 8a54e478bae21305d9a9379ef69b6826962b93c8. As
commit 7dadd3816184 ("Revert "configure: Switch debug build from
-O0 to -Og") was reverted (by b7627085cb134, "Revert "Revert
"configure: Switch debug build from -O0 to -Og""")), we do the
same to cmake to keep the two build systems in sync.

Closes #14286
