libbuiltin/kconfig: Modify coverage function dependencies

Browse Source 
Currently, there are four code coverage statistics implementations:
1. GCC native implementation
2. CLANG native implementation
3. GCC coverage nuttx mini version
4. CLANG coverage nuttx mini version
Coverage Support:

Enable code coverage for all code, it will instrument
all code, which will cause a large performance penalty for the code.
If use GCC, it will add the '-fprofile-generate
-ftest-coverage' parameter to all module.
If use Clang, it will add the '-fprofile-instr-generate
-fcoverage-mapping' parameter to all module.
