Actual global support (#2262)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Use TerminatedUnownedStringSlice for literals in output C++.

* Remove Escape/Unescape functions used in slang-token-reader.cpp
Add target type of 'host-cpp' etc to map to the target types.

* Fix some corner cases around string encoding.

* Added unit test for string escaping.
Fixed some assorted escaping bugs.

* Updated test output.

* Added decode test.

* Stop using hex output, to get around 'greedy' aspect. Use octal instead.

* Added HostHostCallable
Small changes to use ArtifactDesc/Info instead of large switches.

* Fix C++ emit to handle arbitrary function export.

* Add options handling for callable without an output being specified.

* Can compile with COM interface. Added example using com interface.

* Use the IR Ptr type instead of hack in C++ emit for interfaces.

* Fix issue with outputting the COM call when ptr is used.

* Fix crash issue on compilation failure.

* Add support for __global.

* Added `ActualGlobalRate`
Added special handling around globals and COM interfaces.
Tested out in cpu-com-example.

* Fix typo in NodeBase.

* Support for accessing globals by name working.

* Check that actual global initialization is working.

* Refactor the com replacement such that it doesn't need a cache or do anything special with GlobalVar.

* Remove context.
Only create replacement if needed.

* Split out COM host-callable into a unit-test.

* host-callable com testing on C++and llvm.

* Comment around the COM ptr replacement.

* Disable com test on vs 32 bit.
Fix C++ prelude

* Disable 32 bit targets testing com host-callable.

* Use JSON parsing to locate VS version.

* Need platform detection in C++prelude.

* Fix com host callable test for LLVM.

* Work around for not being able to include "targetConditionals.h"
