util: Add extern "C" guard in simple_mtx.h
This is a header that can be accessed both in C/C++,
And when remove the usage of _MTX_INITIALIZER_NP in latter commits, it's need
implement simple_mtx_init in .c file, so for ABI consistence
Add the extern "C" for cpp files
Also add comment for #endif guard for code readability
