Rename and add multiple kconfig compiler options. New compiler options COMPILER_OPTIMIZATION_PERF and COMPILER_OPTIMIZATION_NONE have been added. Optimize "Debug" and "Release" options to "Default" and "Size" respectively. This commit also does the following: - The COMPILER_OPTIMIZATION_PERF option introduced multiple bug. This commit fixes those bugs. - build.yml also updated to test for the new optimization options.
