Ivan Grokhotkov 85a009ad64 Support newlib C library configurations without tm_gmtoff field (#2600) ...

Newlib C library (https://sourceware.org/newlib/) has a configuration
option to add tm_gmtoff field to the tm structure. Not all the
platforms supported by newlib enable this option, and spdlog doesn't
compile on such platforms due to missing tm_gmtoff field.

Fix this by checking for `__NEWLIB__` and `__TM_GMTOFF` and enabling
calculate_gmt_offset.
