Ability to set Paths on Pass Through/Back End Compilers (#1010)

* Expanded prelude for some other resource types. Disable C++ output for ParameterGroup.

* WIP: Layout for CPU.

* Fixes to CPU layout.

* WIP: The uniform is output, but the variable definition is not.

* WIP: Entry point parameters to global scope in C++.
Handling of resource types (in so far as outputting)

* Some discussion of ABI and different input types.

* WIP: More C++ support around resource types.

* WIP: Split up variables into different structures on emit.

* WIP: Emitting C++ with wrapping up of 'Context'

* WIP: C++ code has access to semantic values.
Wrap in struct so can use method calls to pass shared state.
Disable  legalizeResourceTypes and legalizeExistentialTypeLayout

* Fix structured buffer layout for CPU.

* Remove testing/handling of global uniforms on CPU path.
Typo fix.
Changed CPU tests to use new CPU calling convention.

* Check globals are working. Initalize context to zero globals.

* Order the global parameters for C++ ouput by their layout.
Note - that layout isn't quite working correctly because the StructuredBuffer<int> the int seems to be consuming uniform space.

* Work around for reflection not having all data needed for layout ordering for C++ code.

* Output constant buffers as pointers.

* Entry point parameters accessed through pointer to struct.

* WIP: Layout for CPU is reasonable for test case.

* Only output 'f' after float literal if type marks as a float.

* Cast construction works on C++.

* Made IntrinsicOp::ConvertConstruct to make intent clearer.

* C++ handling construction from scalar.
Handle access of a scalar with .x.
Check default initialization.

* Comment about need for split of kIROp_construct.
Release build works.

* Added support from constructVectorFromScalar to C/C++ target.

* Handling of in/out in C/C++.

* First pass documentation CPU support.

* Improvements to C++/C slang code generation documentation.

* Small doc change to include need for mechansim to specify cpp compiler path.

* WIP: Being able to set path for backends.

* Better handling of swizzling - allow swizzling a scalar into a vector.

* Fix missing/broken headers for path setting on session.

* Fix for compiling using clang on Windows.

* Remove Clang test code.

* * Removed spSessionGetGlobalSession - no longer needed because SlangSession is slang::IGlobalSession alias.
* Gave Session a ref count on spCreateSession, and have it checked on spDestroySession, so behaves correctly as ISlangUnknown

Note that spDestroySession does a release (and checks the ref count on debug builds). It's behaviour could be the same as just release, but this seems closer to the original intention.
