rustdoc: fix overflow-wrap for table layouts

For all table layouts, set overflow-wrap: break-word.

Fixes #93135

Demo: https://rustdoc.crud.net/jsha/fix-wrapped-names/std/intrinsics/index.html#functions

(Compare vs https://doc.rust-lang.org/nightly/std/intrinsics/index.html - you may have to make your browser narrower to see the effect)
