Subject: [PATCH] fix: Copies SFCDescriptor before further passing it to
 processors

scss processor modifies descriptor.styles[x].map.mappings and
`parse` function from `component-compiler-utils` caches the parsing
result. These two combined would cause a bug when rolling-up
multiple-output configuration since the descriptor is modified and
cached in the first turn and causing successive turns to fail.
