Breaking changes in PR #182.

[Kangz]

#192 headers contain breaking changes that remove all the enums for the provisional ray-tracing extension. This makes it extremely painful to roll the headers in existing projects because it prevents gradual migration to the new API (even just compilation-wise). This gets even worse for projects that have dependencies that use use the enums from the provisional extension (like the spirv-tools).

Can the WG consider using a Provisional naming scheme next time and if it wants to remove the enums consider deprecating them over time (like ~a year)?

Typo. It was #182

I'll add this to the next withing group agenda for discussion.
