  [lldb] Trim and show embedded zeros in `charN_t` arrays (#195514)

When formatting `char[N]` (N > 0), the read buffer is limited to the
array size and trailing zeros are trimmed.

`charN_t[N]` was treated like a `charN_t *` and the formatter read until
the first zero byte.
If the array doesn't have any zero bytes in it, this will read too much.
If the array has zero bytes in it, it will show too little.

With this PR, `wchar_t[N]` and `charN_t[N]` are printed like `char[N]`.
