Shader caching (#2432)

* Changed all getEntryPointCode calls to use RendererBase::getEntryPointCodeFromShaderCache

* Hashing hooked up, tests pass but need to add more to fully test functionality

* checkpoint

* Checkpoint: File system creation seems functional, saving is broken

* checkpoint: Fixed filename generation from MD5 hash, shader blob might be going missing ahead of pipeline state creation

* Fixed a lot of bugs related to hash code generation, shader cache is likely working but needs further testing

* Added workaround for module loading by re-creating the test device, shader cache test functional

* Vulkan shader caching bug fixed, checkpoint commit before more refinement

* pre-ToT merge checkpoint

* checkpoint commit, improving cache keys

* Significantly expanded items included in the dependency hash for Module; Added dependency hash functions to SpecializedComponentType and RenamedEntryPointComponentType

* Temporarily disable shader cache test

* Mid cleanup changes, solution successfully builds

* Added several helper update functions to slang-md5 to help simplify usage; Added a function under ISession to compute a hash for all linkage-related items; Function renames and cleaned up some comments

* Ran premake.bat; Renamed getASTBasedHashCode to computeASTBasedHash

* Added slang unit tests for Checksum and MD5; Extended gfx shader cache test to test with multiple shader files and one shader file with multiple entry points

* Solution builds and shader cache tests pass, but at least a couple other tests now failing

* ran premake.bat

* More cleanup changes

* Added shaderCachePath field to IDevice desc in gfx.slang, gfx-smoke.slang should be functional

* ran premake

* cleanup changes; Adding test printf to getEntryPointCodeFromShaderCache to see if output can be seen in CI

* Removed debugging printfs; Added handling for getEntryPointCode() failing

* Cleanup changes; Jonathan's fixes to SerialWriter to zero initialize otherwise uninitialized memory; Change to SwizzleExpr creation to zero initialize elementCount

* Changed enable_if_t to enable_if

* Fixed enable_if

* Added test for import vs include and changes to included and imported files; Fixed build errors in CUDA; Renamed shader cache statistics fields

* cleanup changes

* Readd removed file

* Restructured computeDependencyBasedHash calls, added computeDependencyBasedHashImpl to all classes dervied from ComponentType

* Applied same restructuring to the AST hash functions

* Cleanup changes; Moved HashBuilder out to slang-digest.h and added some helper functions to streamline the process of adding items to a hash

* Cleanup; Fixed incorrect expected results for shader import and include test
