RFR: JDK-8301201: Allow \n@ inside inline tags using inlineContent

Fri Jan 27 18:48:56 UTC 2023

Please review a simple change to allow the use of _newline_ _whitespace_ `@` inside inline tags that allow rich content (that is, those parsed with `inlineContent`) as compared to those that only allow plain text (that is, those parsed with `inlineText`).

The fix is to delete the code which recognizes `@` as the beginning of a block tag. Compare to the similar fix in [JDK-8241780](https://bugs.openjdk.org/browse/JDK-8241780)

The general `TagTest.java` is updated for the new feature.
