Iikka Eklund 95cc652e1a Conan: Fix build_type usage in the build recipe 
Currently e.g. -debug-and-release builds are "broken" as it only
produces release binaries on Windows. There are other inconsistencies
also how the recipe deals with various release and debug related options
and how those map the Conan's 'build_type'.

Pick-to: 6.2 6.2.1
