a211184347 Clarified error message; extended error to identifier end 
Lengthening the reported error length to include all of the identifier necessitates scanning for all of the identifier. I also reset the `pos` after so other identifier scanning still happens.

Skip implicit any suggestions with no codefix (#28822) 
The only unsupported one is binding patterns, which aren't supported by the codefix.
The code was a lot faster to write without supporting them, but there's
no real barrier besides that.

Infer from arrows from usage. (#28832) 
* Infer from arrows from usage.

Previously only function expressions were, and only those with an easily
accessible name. Now any arrow function or function expression will
infer from usage.

* remove isApplicableFunctionForInference

*all* functions are applicable for inference now.

Fix crash on property assignment of unresolved module (#28606) 
Previously, the compiler would crash when binding a non-top-level
property assignment on the symbol of an unresolved module:

```js
import x from 'arglebaz'
{
    x.bar = 1
}
```

That's because `x` looks like an alias but doesn't have a
valueDeclaration (since there is no file named 'arglebaz'), and the new
code for binding Object.defineProperty calls forgot to check for an
undefined valueDeclaration.

This change adds the checks for an undefined valueDeclaration.

arguments from outside the function will be the element type.

Better nameless parameter implicit any error (#28554) 
* Initial version, doesn't work for primitives yet.

Need to find out why.

null and void don't even parse without parameter names so they are not
tested.

* Improve error wording

* Add detail to error message
