After #3580 lands and we are generating the iree_hal_executable_library_t interface we can add support for producing static objects (or maybe archives?) as part of the LLVM AOT path. These objects would contain an exported library symbol that can be included in builds by users and the VM-side would embed the same identifier for runtime lookup via a iree/hal/local/loaders/static_library_loader.c interface.

Adding a static library loader. (#5480)
20ce42b 
This allows applications to inject a set of static libraries that can be resolved at runtime by name. This only includes the runtime portion: there's nothing in the compiler actually generating static libraries yet.

Future improvements to the driver API as part of #4298 will make it easier to inject these loaders.

Fixes #4679.
