Cache current thread ID in TLS (dotnet/coreclr#24699)

While looking at the strace of `corerun` built with logging and
debugging information, I was amazed at the number of gettid() calls it
was making.  While system calls are cheap, they're still not free;
cache this number in the thread local storage area.  Adds a branch, but
it's just a comparison with 0, so it's fine in comparison.
