Rollup merge of #75464 - poliorcetics:intra-links-panic-and-ascii, r=…

…jyn514

Move to intra doc links for ascii.rs and panic.rs

Helps with #75080.

@rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc

I also updated the doc to fix the wording in `AsciiExt` since it is now deprecated.
The two file are small changes so I bundled them together.

Some links could not be changed to make them work, I believe those are known issues with primitive types.
