Implement FileCheck tests for several test commands (#2747)

* 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

* Implement FileCheck tests for several test commands

- SIMPLE, SIMPLE_EX
- SIMPLE_LINE
- REFLECTION, CPU_REFLECTION
- CROSS_COMPILE

It does not currently support the render tests or the COMPARE_COMPUTE commands

It is invoked by adding `(filecheck=MY_FILECHECK_PREFIX)` to the test command, for example

TEST:CROSS_COMPILE(filecheck=SPIRV): -target spirv-assembly

* Move LLVM FileCheck interface to slang-llvm

* Neaten slang-test tests

* Refine handling of expected output in slang-test

* Add example FileCheck buffer test

* Add cuda-kernel-export tests

Which were waiting on FileCheck

* Bump vs project files

* Make createLLVMFileCheck_V1 return a void* rather than specifically an IFileCheck

* Remove use of CharSlice from filecheck interface

* Bump slang-llvm version
