Improvements around C++ code generation (#1396)

* * Remove UniformState and UniformEntryPointParams types
* Put all output C++ source in an anonymous namespace
* If SLANG_PRELUDE_NAMESPACE is set, make what it defines available in generated file.

* Fix signature issue in performance-profile.slang

* Context -> KernelContext to avoid ambiguity.

* Fix issues around dynamic dispatch and anonymous namespace.

* Fix typo.
