Storage Kit's ResourceFile class is missing some exception catches

[anevilyak]

While testing x86-64 boot, I was repeatedly running into consoled dying due to a BPrivate::Storage::Exception being thrown and not being caught. After looking through the code, those should be getting caught and hidden from client code at all times, so there's clearly a case being overlooked somewhere. Will dig into it more once x86-64 has support for resolving userland symbols in KDL backtraces, since at the moment it's a bit cumbersome to determine exactly what the culprit is.

Alternatively, exceptions could be broken, too.

Looks like it may have been something stale on my side, not seeing it any more with a complete clean build.
