Steven Wu 7ed9a52633 [PrefixMap] Remap clang cc1 args when building swift interfaces ...

Fix a bug that swift clang importer is not setup correctly when prefix
map is used. There are two separate issues:
* CC1 args used to setup clang import when building swift (interface and
  sources) are not correctly remapped.
* When loading SDKInfo from SDK path, the SDKSettings.json is not
  loading from VFS, thus the file cannot be loaded from remapped path.
