More const {} init in thread_local
`const {}` in `thread_local!` gets an optimization just based on the syntax, rather than the expression being const-compatible. This is easy to miss, so I've added more examples to the docs.
I've also added `const {}` in a couple of places in std where this optimization has been missed.
