cmake: Guard CMAKE_BUILD_TYPE when integrating with Zephyr

Zephyr controls compile and linker flags, such as optimization using Kconfig and not CMAKE_BUILD_TYPE. Therefore disable the setting of CMAKE_BUILD_TYPE when Zephyr is used to avoid situations like `-Os -O2` when compiling Zephyr with Picolibc. Signed-off-by: Torsten Rasmussen <[email protected]>
