PersistentShaderCache integration (#2453)

* Shader cache index integrated into RendererBase; Added test for cache eviction policy (which currently does not pass)

* Restructured main if block in getEntryPointCodeFromShaderCache; Post-rebase cleanup

* undo local testing only change

* Fixed issues causing shader cache tests to fail

* Edited gfx.slang to reflect structural changes to IDevice::Desc and to include ShaderCacheDesc; Modified how the cache is reading in the file from disk; Added a check to the cache eviction policy test that checks for correct order of entries in the cache as well as eight total expected output files for D3D12 and Vulkan

* Removed line in gfx-unit-test.cpp for local testing

* Edited .gitignore to ignore all shaders automatically generated by the shader cache tests and removed the test shaders that were previously added; Review changes, most notably with an overhaul of how the cache eviction policy test handles checking order of entries

* Ran premake; Removed local testing specific line (again)

* Removed expected comparison files from earlier commit; Ran premake

* Edited premake5.lua to also ignore the auto-generated shader files from specific shader cache tests

* Fixed weird indent in premake5.lua
