Avoid heap allocation when truncating thread names

Ensure that heap allocation does not occur in a thread until `std::thread` is ready. This fixes issues with custom allocators that call `std:🧵:current()`, since doing so prematurely initializes `THREAD_INFO` and causes the following `thread_info::set()` to fail.
