cmake: linker: converter arm and common ld scripts into CMake code Converted existing ld script templates into CMake files. This commit takes the common-ram.ld, common-rom.ld, debug-sections.ld, and thread-local-storage.ld and creates corresponding CMake files for the linker script generator. The CMake files uses the new Zephyr CMake functions: - zephyr_linker_section() - zephyr_linker_section_configure() - zephyr_linker_section_obj_level() to generate the same linker result as the existing C preprocessor based scheme.
