Call the OS function to set the main thread's name on program init Normally, `Thread::spawn` takes care of setting the thread's name, if one was provided, but since the main thread wasn't created by calling `Thread::spawn`, we need to call that function in `std::rt::init`. This is mainly useful for system tools like debuggers and profilers which might show the thread name to a user. Prior to these changes, gdb and WinDbg would show all thread names except the main thread's name to a user. I've validated that this patch resolves the issue for both debuggers.

// We can't set the main thread name on Linux because it renames the process (#97191)
Replace ignore-everything with only-arch Combining revisions with only-arch allows specifying that a test only applies to a handful of targets. This allows removing a large amount of repetition in the test suite for tests that do not benefit. The revisions are suboptimal for this for some tests, so they aren't preferred in those cases.
