[JSC] Add JSC shell support for systems that don't provide a working directory

• Component: JavaScriptCore
• Status: RESOLVED INVALID

[Stephan Szabo]

Add support to the JSC shell for systems that don't provide a working directory to user applications (e.g. PlayStation).

* Add in a --working-directory option to set the base working directory for such systems.
* When a directory has been set with the above, convert paths into absolute paths for opening.
  * fetchModuleFromLocalFileSystem says that it expects only absolute paths already, so no changes were made there.
* For PlayStation, do not try to call to getcwd.

Add --working-directory and related code, move to file-scope NeverDestroyed

Trying a NeverDestroyed static in file-scope to avoid -Wexit-time-destructors failures.
