9ee30b1dc2 Fix broken capture in hellovulkancubes example
Amends 339323b999

Capturing a function argument (or any local variable)
by address is a bad idea.

09b852b1d8 examples/: compile with QT_NO_CONTEXTLESS_CONNECT
Examples are usually a good way to get to know a new codebase, do not
teach developers who are new to Qt about the 3-arg connect() to begin
with.

Drive-by changes:
- `this` can't be implicitly captured with [=] in a lambda, instead
  capture by reference
- Update docs related to the sqlbrowser example; the overloaded signal
  it mentions has been removed in Qt6
- In the sqlbrowser example, rename addConnection() (no-arg) overload to
  openNewConnectionDialog, suggested in code review

0e8d347c6a Remove hellovulkanwindow example
The idea being that hellovulkantriangle demonstrates the same things.
As a getting started tutorial hellovulkanwindow is the ideal example,
but then again QVulkanWindow is not something we want to promote much
in Qt 6.

Some of the docs are moved to hellovulkantriangle.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

dfef2e3f3e Clarify the front face winding order in the Vulkan examples
After applying the correction matrix the front face is CW, not CCW.

The examples work either way but fix them up to avoid reader confusion.

8d72aba9e3 Introduce QVulkanWindow
A convenience subclass of QWindow that provides a Vulkan-capable
window with a double-buffered FIFO swapchain.

While advanced use cases are better served by a custom QWindow
subclass, many applications can benefit from having a convenient
helper that makes getting started easier.

Add also three examples of increasing complexity, and a variant that
shows embeddeding into widgets via QWindowContainer.

[ChangeLog][QtGui] Added QVulkanWindow, a convenience subclass of
QWindow.
