[CMAKE] Rely less on CMAKE_BUILD_TYPE variable
Having conditional statements with CMAKE_BUILD_TYPE is an antipattern
See https://stackoverflow.com/questions/66079007/having-conditional-statements-on-build-type-variable-a-good-design

We use both single- and multi-config generators (Ninja and VS), so we
can't really rely on CMAKE_BUILD_TYPE, because it's not always set.

This commit alters some conditional flags to use <$CONFIG:...>
generator expression, but is still not complete. Also, our default
optimization level (4) now has what was always a de-facto flags
