The density of Q_FOREACH uses is high here, too high for this author
to tackle in a short amount of time. But they're concentrated in just
a few TUs, so pick a different strategy:
Mark the whole plugin with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. Since the TUs are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too). I'm aware that Objective-C/C++ files are
currently probably implicitly NO_PCH_SOURCES, but don't rely on that.

During the Qt 5 -> Qt 6 and qmake -> CMake porting time frame, it was
decided to keep resources in an object file (object library), rather
than putting them directly into a static library when doing a static
Qt build, so that the build system can take care of linking the
object file directly into the executable and thus not forcing
project developers to manually initialize resources with
the Q_INIT_RESOURCE() macro in project code.
This worked for most qmake and cmake projects, but it created
difficulties for other build systems, in the sense that these projects
would have to manually link to the resource object files, otherwise
they would get link time errors about undefined resource symbols,
assuming they kept the Q_INIT_RESOURCE() calls.
If the project code didn't contain Q_INIT_RESOURCE calls, the
situation would be even worse, the linker would not error out,
and the missing resources would only be discovered at runtime.
It's also an issue in CMake projects that try to link to the
library files directly instead of using the library target names,
which means the object files would not be automatically linked in.
Many projects try to do that because we don't yet offer a convenient
way to install libraries and reuse them in other projects (the SDK
case), so projects end up shipping only the libraries, without the
resource object files.
We can improve the situation by moving the resources back into their
associated static libraries, and only keeping a static initializer as
a separate object file / object library, which references the actual
resource initializer symbol, to ensure it does not get discarded
during linking.
This way, projects that link using targets get no behavior difference,
whereas projects linking to static libraries directly can still
successfully build as long as their sources have all the necessary
Q_INIT_RESOURCE calls.
To ensure the resource symbols do not get discarded, we use a few new
private macros. We declare the resource init symbols we want to keep as
extern symbols and then assign the symbol addresses to volatile
variables.
This prevents discarding the symbols with the compilers / linkers we
care about.
It comes at the cost of an additional static initializer per resource,
but we would get the same + a bigger performance hit if we just used
Q_INIT_RESOURCE twice (once in the object lib and once in project
code), which internally needs to traverse a linked list of all
resources to check if a resource was initialized or not.
For GHS / Integrity, we also need to use a GHS-specific pragma to keep
the symbols, which we currently use in qtdeclarative to ensure qml
plugin symbols are not discarded.
The same macros will be used in a qtdeclarative change to prevent
discarding of resources when linking to static qml plugins.
A cmake-based test case is added to verify that linking to static
libraries directly, without linking to the resource initializer
object libraries, works fine as long as the project code calls
Q_INIT_RESOURCE for the relevant resource.

The Android QPA implementation requires a 1:1 link between a platform
window and a platform backing store, to correctly flush a backing
store to the screen. QAndroidPlatformBackingStore has a bool member
m_backingStoreSet, to remember if this link exists. It defaults to
false and is set to true, when setBackingStore() is called in the
constructor. It falsely remains true, when a platform window is
deleted, e.g. because a QWindow has been hidden. When the QWindow is
shown again, a new Android platform window is created. With
m_backingStoreSet still being true, this new platform window will
never be associated with a backing store. As a consequence, it will
never be displayed on the screen.
The 1:1 relationship of an Android platform window and an Android
backing store is neither ideal, nor in line with other QPA layers
(e.g. XCB). Changing the Android QPA implementation is complex and a
short term fix is necessary.
This patch removes the member m_backingStoreSet. Instead of it,
QAndroidPlatformBackingStore::flush() directly checks, if the platform
window corresponding to the QWindow argument is associated to a backing
store. If that is not the case, setBackingStore() is called.
