config_tools: change representation of build types

Instead of using a Boolean variable indicating whether a build is for debug
or release, it is more intuitive to specify the build types as "debug" or
"release".

This patch converts the config item RELEASE to BUILD_TYPE which takes
"debug" or "release" as of now.

The generated header and makefile still uses RELEASE, and the command line
option RELEASE=<y or n> is also preserved.
