b1092a7d42 tst_QPrinter: stabilize qprinter test
The CreationDate entry in the two PDF files can potentially
be different depending on when the test is run.
97b4c5a574 already accounts for it but
the current tag for creation date is '/CreationDate'. Therefore check
if the line contains 'CreationDate' instead.

3e001feb4d If the page size is not valid on the new printer, set a custom size
When the page size was not valid on the new printer, it would end up
having the wrong page size name on the new printer. What should happen
in this case is that it should set the originally set page size as a
custom page size on the printer instead.

b49a2e671a tst_QPrinter: Use qWaitForWindowActive() to wait for dialog
Instead of an unconditional wait.

The QSKIP is necessary because the PDF format is non-native and the Windows
implementation of QPrintDialog doesn't work then.

The macOS implementation has the same warning, so add the check for that OS
as well.

The test has previously passed, since it hasn't seen not actually opening the
dialog as an issue.

1ffe39dfd1 Make it possible to disable font embedding
When font embedding is explicitly disabled, fall back to painter paths
as we would if the font prohibits embedding. Note that this flag was
never respected on any platform in any version of Qt, as far as I've
been able to tell, because the handling of it in the X11 print
engine was removed shortly after it was introduced in 2005.

27473f19bb QPrintEngine - Fix PPK_DocumentName
Add support to the Mac print engine for set/get the Document Name using
the Job Name setting. Our documentation states this is one use that the
document name will be put to so is appropriate to be used.

Change the Windows print engine to default to a blank Docuemnt Name
consistent with the other print engines. If still blank when printing
then use a default value.

053bee8b80 QPrinter - Clean up Print Engine Key defaults and tests
The PrintEngine keys are not consistently treated across the platforms
and are not properly tested.  Start the process of making the print
engines behave consistently by documenting and testing the current
behavior. Ensure all unsupported features return a consistent
default value.

The auto test for valuePreservation() has been flaky depending on the
platform and installed printers so remove it and replace it with more
complete testing.  If no native printers available then don't test
the native engines.

Fixes for the individual inconsistent keys will follow.

e8a45152b5 QPrinter - Fix OutputFormat when no printers
Currently the QPrinter constructor, setOutputFormat() and
setPrinterName() make bad assumptions about the availability of printers
when configuring NativeFormat which can lead to inconsistent print
engine set-ups leading to crashes in the print dialog, especially on
Windows where a valid DEVMODE is needed.

This change cleans up the init and methods to ensure NativeFormat can
only ever be set if we have both a valid plugin and a valid printer,
if not the PdfFormat is used.  One side-effect of this is that it is
now impossible to set an invalid printer name via QPrinter (but still
able to be done via QPrintEngine if really needed).  Also if no
default printer is set then use the first available one.

This also fixes a bug where setting a new printer name on Windows
reset all the saved settings.

[ChangeLog][Important Behavior Changes] QPrinter no longer allows you
to set an invalid printer name.
