* Add basic support for entry points in `.slang-lib` files.
The basic idea here is that when writing out a `.slang-lib` file based on a compile request, we include new sections in the generated RIFF that represent the entry points that were requested. The entry-point information is serialized in an entirely ad hoc fashion (a future change might clean it up to use the `OffsetContainer` machinery), and contains the name, profile, and mangled symbol name of an entry point.
When deserializing this information, we create a list of "extra" entry points that gets attached to the front-end compile requests. These "extra" entry points get turned into `EntryPoint` objects at the same place in the code that entry points specified on the command line or via API would be checked, but the extra entry points bypass the semantic checking and just create "dummy" `EntryPoint` objects.
Aside: the ability for a compile request to end up with entry points that weren't originally specified via API or command-line is not new. We already had support for compiling a translation unit with entry points entirely specified via `[shader(...)]` attributes, and this new support tries to function similarly.
Because the "dummy" entry points don't retain AST-level information, several parts of the code have been modified to defensively check for `EntryPoint` objects without a matching AST declaration, and skip over them.
The main place where this creates a problem is paramete binding, where ignoring the dummy entry point is appropriate since we currently assume linked-in library code has been laid out manually.
One small cleanup here is that the `-r` command-line flag and the `spAddLibraryReference` API functio now bottleneck through a common routine to do their work, so that they both gain the new behavior without needing copy-paste programming.
In order to keep the existing test case for library linking with entry points working, I had to add a flag to the `render-test` tool so that it can skip specifying entry point names as part of the compile request it creates. In that case it must instead assume that the entry points will be added to the compile request via other means. This logic is a bit magical, and hints that we should be looking for other ways to expose the library linking functionality over time.

* Added RiffReadHelper
* Move type to fourCC in Chunk simplifies some code.
* Make MemoryArena able to track external blocks.
Allow ownership of Data to vary.
Changed IR serialization to use moved allocations to avoid copies.
As it turns out all of the array writes could use unowned data, but doing so requires the IRData to stay in scope longer than IRSerialData, which it does at the moment - but perhaps needs better naming or a control for the feature.

* Strip IR after front-end steps are done
The main feature of this change is to unconditonally strip out the `IRHighLevelDeclDecoration`s in an IR module once the "mandatory" IR passes in the front end have run. This ensures that later IR passes (e.g., code emission) *cannot* rely on AST-level information to get their job done.
Since I was already writing a pass to remove some instructions at the end of the front-end passes, I went ahead and also made the `-obfuscate` flag apply to the front-end IR generation by causing it to strip `IRNameHintDecoration`s while it is doing the other stripping. With this, the main identifying information left in IR modules (other than semantics and entry-point names) is mangled name strings for imported/exported symbols.
A few other things got changes along the way:
* Removed the `.expected` file for one of the tests, where that file seemingly shouldn't have been checked in at all.
* Updated the signature of the DCE pass both so that it doesn't require a back-end compile request (it wasn't using it anyway), and so that it takes some options to decide whether to keep symbols marked `[export(...)]` alive (the front-end wants to keep these, while back-end passes currently need to be able to eliminate them).
* Moved the `obfuscateCode` flag from the back-end compile request to the base class shared between front- and back-end requests, and updated the options and repro logic to set both as needed. An obvious improvement in the future would be to have the front- and back-end requests share these settings by referencing a single common object in the end-to-end case, rather than each having their own copy.
* Removed logic that was keeping layout instructions alive in DCE, even if they weren't used. This seems to have been a vestige of an intermediate step between AST and IR layout.
* fixup: add the new files
