Rollup merge of #137281 - estebank:doc-comment-syntax-error, r=compiler-errors 
Tweak "expected ident" parse error to avoid talking about doc comments

When encountering a doc comment without an identifier after, we'd unconditionally state "this doc comment doesn't document anything", swallowing the *actual* error which is that the thing *after* the doc comment wasn't expected. Added a check that the found token is something that "conceptually" closes the previous item before emitting that error, otherwise just complain about the missing identifier.

In both of the following cases, the syntax error follows a doc comment:
```
error: expected identifier, found keyword `Self`
  --> $DIR/doc-before-bad-variant.rs:4:5
   |
LL | enum TestEnum {
   |      -------- while parsing this enum
...
LL |     Self,
   |     ^^^^ expected identifier, found keyword
   |
   = help: enum variants can be `Variant`, `Variant = <integer>`, `Variant(Type, ..., TypeN)` or `Variant { fields: Types }`
```
```
error: expected identifier, found `<`
  --> $DIR/doc-before-syntax-error.rs:2:1
   |
LL | <>
   | ^ expected identifier
```

Fix #71982.

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and interpret a test.

As part of an ongoing effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as a legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
