[sanitizer] Move GetThreadStackAndTls from TSan to sanitizer_common.

Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).
