* Revise new COM-lite API
This change revises the "COM-lite" API that was recently introduced to try to streamline it and introduce some missing central/base concepts.
The central new abstraction in the API is the notion of a "component type," which is a unit of shader code composition. A component type can have:
* IR code for some number of functions/types/etc.
* Zero or more global shader parameters
* Zero or more "entry point" functions at which execution can start
* Zero or more "specialization" parameters (types or values that must be filled in before kernel code can be generated)
* Zero or more "requirements" (dependencies on other component types that must be satisfied before kernel code can be generated)
Both individual compiled modules, and validated entry points are then examples of component types, and we additionally define a few services that apply to all component types:
* We can take N component types and compose them to create a new component type that combines their code, shader parameters, entry points, and specialization parameters. A composed component type may also include requirements from the sub-component types, but it is also possible that by composing thing we satisfy requirements (if `A` requires `B`, and we compose `A` and `B`, then the requirement is now satisfied, and doesn't appear on the composite).
* We can take a component type with N specialization parameters, and specialize it by giving N compatible specialization arguments. The result of specialization is a new component type with zero specialization parameters. Under the right circumstances the specialzed component type will be layout compatible with the unspecialized one.
* One more example that isn't exposed in the public API today is that we can take a component with requirements and "complete" it by automatically composing it with component types that satisfy those requirements. This can be seen as a kind of linking step that pulls together the transitive closure of dependencies.
* We can query the layout for the shader parameters and entry points of a component type, for a specific target.
* We can query compiled kernel code for an entry point in a component type (for a specific target). This only works for component types with zero specialization parameters and zero requirements.
The idea is that by giving users a fairly general algebra of operations on component types, they can compose final programs in ways that meet their requirements. For example, it becomes possible to incrementally "grow" a component type to represent the global root signature for ray tracing shaders as new entry points are added, in such a way that it always stays layout-compatible with kernels that have already been compiled.
Much of the implementation work here is in implementing the unifying component type abstraction, and in particular re-writing code that used to assume a program consisted of a flat list of modules and entry points to work with a hierarchical representation that reflects the underlying algebra (e.g., with types to represent composite and specialized component types).
There's also a hidden "legacy" case of a component type to deal with some legacy compiler behaviors that can't be directly modeled on top of the simple algebra with modules and entry points.
This API is by no means feature-complete or fully developed. It is expected that we will flesh it out more when bringing up application code (e.g., Falcor) on top of the revamped API.
One notable thing that went away in this change is explicit support for "entry point groups" and notions of local root signatures (especially the Falcor-specific handling of the `shared` keyword, which a previous change turned into an explicitly supported feature). With the new "building blocks" approach, it should be possible for a DXR application to deal with local root signatures as a matter of policy (on top of the API we provide). If/when we need to provide some kind of emulation of local root signatures for Vulkan (and/or if Vulkan is extended with an explicit notion of local root signatures), we might need to revisit this choice.
* Fix debug build
There was invalid code inside an `assert()`, so the release build didn't catch it.
* fixup: warnings
* fixup: more warnings-as-errors
* fixup: review notes
* fixup: use component type visitors in place of dynamic casting

* Start exposing a new COM-lite API
This change is mostly about exposing a new API to the Slang compiler that allows more fine-grained control over the compilation flow. The basic concepts in the new API are:
* An `IGlobalSession` is the granularity at which we load/parse the Slang stdlib, and therefore gives applications a way to amortize startup cost for the library across multiple compiles. This is a concept that might be able to go away in a future version of Slang.
* An `ISession` owns all the code that gets loaded/compiled/generated. Any `import`ed modules are shared across everything in a session (we don't re-parse/-check the code when we see another `import` for the same module). Any generic- or interface-based code in the session can be specialized using types from the same session (but not necessarily across sessions).
* An `IModule` is the unit of code loading and scoping. It doesn't expose any API in this change, but would be the right scope for looking up types or entry points by name.
* An `IProgram` is a "linked" combination of modules and entry points from which code can be generated and reflection information queried.
This change re-uses the existing reflection API types, rather than introduce a new API that duplicates that functionality. That will probably change in a future revision.
There are two major pieces of functionality added here that aren't related to the new API:
* We now have an API concept of "entry point groups" which are one or more entry points that are intended to be used together so that they need to have non-overlapping parameters. For now this is being used to handle "hit groups" and local root signatures for ray tracing, but I'm not sure this is a concept we will keep in the long run.
* We have a very special-case (client-application-specific) flag that ascribes special meaning to the `shared` keyword, so that it can be attached to global parameters to indicate that they are actually to be part of the local root signature rather than the global one for DXR.
None of the API design (including naming) here is finalized; the only reason to check in the changes at this point to avoid having a long-running branch that leads to merge pain. Clients should *not* try to depend on the new API just yet, since it is still a work in progress.
* fixup: clang warning
* fixup: try to detect clang C++11 support
* fixup
