Cocoa: Clear window hash entry in ~QCocoaWindow.

The Cocoa platform plugin maintains a NSWindow->
QCocoaWindow hash.

Hash entries was not properly cleared on QCocoaWindow
destruction. Add call to clear the entry for the
destroyed window. Make QCocoaIntegration remove
the key from the hash in this case instead of
setting it to 0.

ANGLE WinRT: Create swap chain using physical resolution

ANGLE has been creating the framebuffer in logical pixels instead of
physical pixels, which leads to unexpected results and side effects like
smudged anti-aliased text. This fixes the issue by multiplying the DIP
resolution by the scale factor, making the framebuffer match the physical
pixel resolution of the screen.

WinRT: Support High-DPI

Previously, the backing store and default framebuffer were created with
the logical screen resolution (in device-independent pixels), not the
the physical screen resolution. This lead to blurry text on high-DPI
devices. This change fixes this by creating those at full size, and
setting the device pixel ratio appropriately. Windows are still reported
in device-independent pixels, but text and images are now rendered
sharply for Qt Quick applications.

As QPainter does not support non-integer scaling, the backing store is
still drawn in DIPs and scaled by OpenGL.

Direct2D QPA: Fix HighRes painting

It turns out that supporting HighRes painting with Direct2D is quite
simple. Two things are necessary.

First, we set the unit mode to D2D1_UNIT_MODE_PIXELS on all our device
contexts, which tells Direct2D that we specify everything in pixels.
Direct2D will internally do the required conversions.

Second, we scale font sizes according to DPI.

Previously rendering errors resulted when a highres mode was used, this
fixes those errors.

Call doneCurrent on QOpenGLContext when the surface dies

Doing makeCurrent() followed by destroying the surface (and no
doneCurrent) results in still having the pointer stored internally
in the QOpenGLContext. If then a function like defaultFramebufferObject()
is called, the pointer is dereferenced.

To fix this, the doneCurrent() has to be called when the surface is destroyed
before the context without doneCurrent(). This is pretty much what the
user would expect anyhow.

we need to store commands with system path separators in the .pri files,

are actually bound to the host system, not the shell.

we also need to shell-quote the commands, as whitespace, and more
commonly windows path separators in an msys shell, would break things.
we delay this to the last moment possible, as it does depend on the
shell.
