On THD::reset, typecast the result of query_start_sec_part() to tv_usec in a more portable way. Previously, we assumed that the left hand side was always long-compatible but that isn't the case on mac.

Code Review
This pull request updates the reset method in sql/sql_class.h to cast thd->query_start_sec_part() to the type of tv_usec using static_cast<decltype(tv_usec)> instead of a C-style (long) cast. This improves portability across different operating systems, such as macOS, where tv_usec may have a different underlying type. There are no review comments, and I have no additional feedback to provide.
