Rollup merge of #112345 - bvanjoi:fix-112342, r=nilstrieb,est31
fix(expand): prevent infinity loop in macro containing only "///" Fixes https://github.com/rust-lang/rust/issues/112342 Issue #112342 was caused by an infinity loop in `parse_tt_inner`, and the state of it is as follows: - `matcher`: `[Sequence, Token(Doc), SequenceKleeneOpNoSep(op: ZeroOrMore), Eof]` - loop: | Iteration | Action | | - | - | | 0 | enter `Sequence`| | 1 | enter `Token(Doc)` and `mp.idx += 1` had been executed | | 2 | enter `SequenceKleeneOpNoSep` and reset `mp.idx` to `1` | | 3 | enter `Token(Doc)` again| To prevent the infinite loop, a check for whether it only contains `DocComment` in `check_lhs_no_empty_seq` had been added.
