Feature/test tool shared libraries (#758)

* Remove circular reference to renderer on Vk & D3D12 DescriptorSetImpl

* Refactor Stbi image loading such that memory is correctly freed when goes out of scope.
Added Crt memory dump at termination.
Reduced erroneous reporting by scoping TestContext.

* Used capitalized acronym for STBImage to keep Tim happy.

* Split out TestReporter - to just handle reporting test results
Split out Options
Made TestContext hold options, and the reporter
Removed remaining memory leaks.

* Small optimization for rawWrite, such that it directly writes over print..

* Improve comments on TestCategorySet

* Fix typos in TestCategorySet

* Made slangc a cpp file as part of slang-test (removing need for separate project/shared library).

* * Made all test tools only available as dlls.
* Made possible to invoke test tool dll from command line

slang-test slangc [--bindir xxx] options to slangc

* Fix Visual Studio projects that are no longer needed.
