box: fix setting box error name

Currently we fail to set box error name is some cases. Error name is
error payload with key `name`.

Let's cleanup error code a bit. As result the bug will be fixed.

1. Use `va_list` in error constructors so in order to remove error
   reinitialization in build functions.
2. Use ClientCode for building ER_UNSUPPORTED_INDEX_FEATURE. It is
   ClientError too.
3. Drop tnt_error() which has a single usage.
4. Drop logged error. It is just a ClientError that is logged when
   created.

Closes #10708
