In MachExceptionInfo constructor, update the AVX registers using thread_get_state.
This fixes #78991.
We found that the null reference exception happened because we were not updating the upper half of the ymm register in the MachExceptionInfo. This caused only part of a structure to be copied from the ymm register to a new location. Instead of the second half of the structure in the new location, there were zeros.
