fix: No Longer Resourcing Defconfig during build
When building, the cmake environment would rerun the configuration
stage, including sourcing the original defconfig and overriding the
local .config. Now the config.cmake is generated when the defconfig is
sourced, and if it exists already, then the defconfig is ignored.
