tools: regions only if bootloader is supported

We removed catching and passing, we want to know for any misconfiguration if bootloader
is supported. Regions should check if bootloader is supported. In case not, just return.
Otherwise we catch any error.

This should help us to uncover missing regions or other config error (in case bootloader
is enabled via bootloader_supported set to true).
