`encodeUtf` and `decodeUtf` incorrectly catch asynchronous exceptions

[wz1000]

encodeWith and decodeWith use try @SomeException to catch all exceptions that may arise while dealing with C buffers.

See for instance

os-string/System/OsString/Common.hs

Line 239 in 06a9edc

r <- try @SomeException $ GHC.withCStringLen enc str $ \cstr -> WindowsString <$> BS8.packCStringLen cstr

This is incorrect, as asynchronous exceptions thrown to such code (for instance using killThread or ^C) should not result in a EncodingException.

The simplest way to fix it is to see if the exception is SomeAsyncException and if so reraise it.
