At starts jsdoc tag only after whitespace (#42364)
* Update tests

* @ begins JSDoc tag only after whitespace

Previously, inside a JSDoc tag's comment, @ would start a tag unless it
was surrounded by backticks. However, looking at real code showed that
only whitespace-preceded uses of @ were intended to start tags.

fix: const enums + isolatedModules emit invalid code (#41933)
* chore: failing test for const enums and isolatedModules

* fix: const enums + isolatedModules emit invalid code

In `isolatedModules` mode, the compiler does not inline const enums,
but also decides not to `import` them, leaving invalid code that
throws a `ReferenceError` at runtime.

This code:

```
import { SomeEnum } from './bar';
sink(SomeEnum.VALUE);
```

..should compile to either:

```
var { SomeEnum } = require('./bar');
sink(SomeEnum.VALUE);
```

..or (with const enum inlining):

```
sink(1 /* VALUE */);
```

..but actually compiles to:
```
sink(SomeEnum.VALUE);
```

..with no imports, which throws a ReferenceError at runtime.

---

The compiler has already realised that the symbol is a referenced const
enum, it just doesn't use this information when it comes to deciding
whether to emit an import. This commit additionally checks that
information, if we are compiling in isolatedModules mode.

---

In my opinion, this is not the correct fix, but it is the simplest. In
`isolatedModules` mode, `const enum` should probably be a compile error
(because there are no benefits and the complexity is high, and,
apparently, buggy). If not, the compiler should not be checking whether
something is a const enum, and should just be treating it as a regular
enum, and checking as if it was?

Fixes #40499.

* chore: extra test for type-only

* feat: explicitly ban --isolatedModules --preserveConstEnums false

* feat: isolatedModules implies preserveConstEnum

* Update src/compiler/diagnosticMessages.json

Improve naming of hasNonBindableDynamicName (#42297)
hasNonBindableDynamicName

1. Has 'non' in the name, and is only ever used negated.
2. Is true for a case that's not reflected correctly in the name -- it's
true for non-dynamic names as well.

I considered hasEarlyOrLateBindableName, but decided to use
hasBindableName for now.

Shrink error span on @type errors for signatures (#42024)
Previously, the error span was too large on @type errors on functions
when the type was not a function. The span covered the entire tag. This
PR changes the error node just to be the type of the type tag. In other words,
the error span was previously this:

```
@type {IncorrectType}
```

But is now just this:

```
IncorrectType
```

Fixes the first error from #41974, but not the other two.
