Add QFileInfo::isNativePath
This function returns true if the file path can be used directly with
native APIs, modulo encoding and path separator conversions. This is
important for applications that interface with other libraries or simply
need to use native APIs together with Qt.
Traditionally, this information was available in QAbstractFileEngine and
forced users to explicitly create an engine or use internal API such as
QFile::fileEngine to access the underlying engine and this piece of
information.
Given its usefulness, exposing the information in a more visible place
is more appropriate. This reduces the need for people to know or care
about implementation details, like file engines...
The existing isLocalFs test was updated and repurposed to use the new
API, instead of relying on file engines and internal implementation
details of QFileInfo.
