[Clang] Fixed the behavior of C23 auto when an array type was specified for a char * (#189722 )

At the time of the implementation of
[N3007](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3007.htm) in
Clang, when an array type was specified, an error was emitted unless the
deduced type was a `char *`.
After further inspection in the C standard, it turns out that the
inferred type of an `char[]` should be deduced to a `char *`, which
should emit an error if an array type is specified with `auto`.

This now invalidates the following cases:
```c
auto s1[] = "test";
auto s2[4] = "test";
auto s3[5] = "test";
```

Fixes #162694
