Sync LinkPlayer Struct with pokeemerald

In pokefirered, the `LinkPlayer` struct used an 11-byte name field and puts extra link-related info in the last three bytes. pokeemerald separates these last three bytes into their own fields. This commit replicates how pokeemerald handles those fields.

Also renamed `IntlConvertLinkPlayerName` to pokeemerald's `ConvertLinkPlayerName` because I was there and noticed it.
