Checkpoint

This is what I think the copyright notice should be.  I started with
"revision 10" of the copyright template here:
https://members.khronos.org/wg/General/document/25728
and I removed the optional sections that don't seem to apply to us.

However, the existing notice in the SYCL 2020 spec seems to contain
some paragraphs from these two optional sections:

*	Optional 'Normative Wording' Start - ONLY use if Working Group
  explicity requests restating of the Khronos Intellectual Property
  Rights Policy
* For specifications with Normative References to other specification
  that are created externally to Khronos

Personally, I don't think those apply to us.  However, if we want to
include them, I think we need to include all paragraphs from those
optional sections.
