Move-enable QSignalBlocker

When QSignalBlocker was reviewed, move semantics were asked for.
This patch add them.

This makes QSignalBlocker usable as a by-value argument (to transfer
control of signal blocking into a function) as well as as a return
value (to transfer control of signal blocking out of a function).

tst_QObject: separate QSignalBlocker tests

tst_QObject is getting big, so make a separate test for QSignalBlocker,
but leave parts of signalsBlocked() in tst_QObject as that seemed to
have been the only check for blockSignals(true) actually blocking signal
emission.

QLineEdit: hide placeholder text when h-centered & focused

[ChangeLog][QtWidgets][QLineEdit] A blinking cursor in the middle
over horizontally centered placeholder text looks bad. Thus,
horizontally centered content is now considered as an exception
and the placeholder text is hidden when the line edit is focused.

Moved d3dcompiler from src/angle to src/angle/src

Even though it is not really part of the angle implementation, having it
in source is more consistent with the rest of Qt and makes browsing the
code easier.

There was also an issue, that only a debug build was done when calling
nmake or jom. While moving the implementation this issue was fixed by
including config.pri to d3dcompiler's .pro file.

Automatically create QPainterPathStroke based on QPen

Based a recent problem where one property of QPen was not properly copied
to QPainterPathStroke, I believe we should add a method to automatically
create a QPainterPathStroke based on all the relevant information in a QPen.

This patch adds a constructor that automatically does so.

QNX: Fix focus handling for secondary screen

This patch removes the activaton aand deactivation of a window when we get the window group
activated event from the navigator. This event is sent to both the primary and secondary screen
and does not state if a window should be active from a Qt perspective.
A window should only be active if it has screen keyboard focus.
