More about about Fix kernel argument definition for named function objects

### Specification Version

SYCL 2020 (Revision 11)

### Section Number(s)

Somewhere

### Issue Description

Follow-up on #996

- Kernel paramebers rule always to the`member` of the kernel, but not to the kernel type itself.
- Is this is a problem? (At least, we agree it seem weird)

----

Will add ping to Tom when he can : )

### Code Example (Optional)

_No response_

Start by reading the linked context in #996 and the SYCL 2020 kernel parameter rules. The issue does not identify a specification section or repository file, so first locate the relevant text and determine whether the rule applies to the kernel member or kernel type. Done means resolving that question and updating the appropriate specification wording.
