Subject: Convert gfx unit tests and examples to use slang-rhi (#7577)

* Port first gfx unit test to slang-rhi

* port triangle example to use slang-rhi

* port platform-test to slang-rhi

* Update platform-test to throttle mouse move events

* port gpu-printing example to use slang-rhi

* port model-viewer example to use slang-rhi

* port ray-tracing example to use slang-rhi

* port ray-tracing pipeline example to use slang-rhi

* port reflection parameter blocks example to use slang-rhi

* port shader-object example to use slang-rhi

* port shader-toy example to use slang-rhi

* Port most of tests to slang-rhi

* port link-time-constant-array-size to use slang-rhi

* Fix tests and find matching tests in slang-rhi

* port autodiff-texture

* remove gfx target; port nv-aftermath-example

* update include path for shader-cursor.h

* Disabled 2 more ported tests

* fix build error

* remove gfx test

* put slang-rhi (static-lib) before slang (shared)

* format code (#7621)

Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

* add debug callback

* format code (#7649)

Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

* Address review comments; revert back to use SLANG_CHECK_MSG
