Fix QPrinter test in Windows

Browse Source 
Fixed Q_WS_WIN flagging to Q_OS_WIN in QPrinter API and related
implementation to make API match the documentation and Qt 4.8.
Also Removed the unused internal HDC related functions from the API,
that were previously behind Q_WS_WIN flag.

Some of the properties tested are documented to be valid for native
print engine only in X11 environment, so skipped testing those in
non-xcb environments.

Copy collation is also apparently not supported in Windows native print
engine, though this seems to be undocumented, so skipped that only in
Windows.

At least one of the test blocks in tst_QPrinter::valuePreservation()
failed due to default printer not getting set properly, so fixed that,
too.
