Build: Add macro for enabling code coverage flag
Add TFM_CODE_COVERAGE for GNU compiler to output more symbol info
by the parameter "-g".
The code coverage will be disabled by default.
Define TFM_CODE_COVERAGE=True to enable the code coverage flag when
build.
This is a preparation for code coverage analysis after the binary run.
And the code coverage report will rely on the symbol info for
calculating.
