refactor(libc): clean up dependencies in libc
- Removing platform dependencies from libc modules.
- Replacing panicking with actual error handling.
- Debug macros are included indirectly from assert.h. Removing
"platform_def.h" from assert.h and adding "common/debug.h"
where the macros are used.
- Removing hack for fixing PLAT_LOG_LEVEL_ASSERT to 40.
Instead removing assert with expression, as this
does not provide additional information.
