Subject: Fix several silently failing tests (#2767)

* Add missing expected.txt for test

* Diagnostics -> StdWriters in render test

* Allow specifying several test prefixes to run

`slang-test -- tests/foo tests/bar`

* Squash warnings in some tests

* Enable gfx debug layer in gfx test util

Makes this issue present consistently: https://github.com/shader-slang/slang/issues/2766

* Allow DebugDevice to return interfaces instantiated by the debugged object

* Check that we actaully have a shader cache for shader cache tests
