  Log Message:
  -----------
  [clangd] support expanding `decltype(expr)`

Enable the existing tweak `ExpandAutoType` to expand
`decltype(expr)`, e.g.

```
decltype(0) i;
```

will expand to

```
int i;
```

Therefore, rename the tweak `ExpandAutoType` to `ExpandDeducedType`.

This patch also fixes some nits,

* avoid replacing reference to a function
* avoid replacing array types and reference to an array
