Fix cross-references in Clang attribute reference (#142967)

Anchors are automatically generated, but adding another anchor with the
same name hides the anchor that we actually want. Simply removing the
unnecessary self-referential anchor `lifetimebound` fixes the links.

The documentation for coro_disable_lifetimebound and coro_lifetimebound
also had an unnecessary redirection. It's possible to change the link
text to differ from the heading, but I think that's not necessary here.

Also fix a reference in clang-tidy that was using the (unstable)
numbered anchor.
