Improvements around HLSLToVulkanLayout (#2867)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Improve the HLSLToVulkanLayoutOptions interface.
Add more diagnostics.
Add diagnostics test.

* Add check for global binding using file check.

* Fix issues with some tests around making some diagnostics ids unique.

* Small improvements with doc/handling of vk-<>-shift option setup.
