This reverts commit bc86f2b91c76f0e40ad60516dcb1031d02e7054b.

* Remove platform specific naming

* [tasks] Move App Context setup back to autoinit.c

* Remove registering bundled modules and debugging until they can be validated

* Remove unnecessary wrapper

* Grab bundle_path later without eglib

so grab it first thing when initializing the runtime.

Use getenv directly instead of calling into eglib with just one api

* Move assembly loading into separate function

* Remove unnecessary function

* Cleanup CMakeLists template indentation

* Load assemblies with partial name

* Clean up targets and unneeded properties

* Rename source file

* Remove preload hook and make out of memory error more generic

* Throw when no exported symbols are found

* Remove aot data load prehook and aotdata generation

* Address feedback

* Address more feedback

* Add various fixes and make bundle_path a local variable

* Reintroduce load aot data hook in autoinit with guard

* Fix closing tag

* Include guard library-builder.h

* Fix typo
