Add unqualified JSDoc member references (#44202)
* Add unqualified JSDoc member references This allows unqualified references like: ```ts class Zero { /** @param buddy Must be {@link D_HORSE} or {@link D_DOG}. */ deploy(buddy: number) { } static D_HORSE = 1 static D_DOG = 2 } ``` I surveyed @see and @link again to estimate how common this is. I found a little over 200 uses, which is around 2%. Sorted by frequency, this *is* the next feature on the list, along with the `module:` prefix. So I think this is about the right point to stop adding code. In this case, however, I liked most of the uses -- there were a lot of deprecated functions that referenced a function just below, where it would be wordy to qualify the name, but the reader would benefit from a link. Note that unqualified references do *not* work inside type or object literals. The code I ended up with is quite complicated and I didn't observe any uses in the wild. Fixes #43595 * Remove type/object literal container check Since they don't work anyway
