The problem with non-legacy mode is that the backend uses the same
filename for the system semaphore file and for the shared memory file.
What happens is that when we try to call attach(), a semaphore is
created. Later in attach() we set unix_key, because ftok() returns
a valid handle (it uses the file which was created for semaphore).
After that, an attempt to actually attach to a shared memory fails, but
no clean-up is done.
So, a later call to create() sees that unix_key is already valid, but
it cannot properly clean it, because it does not actually refer to
any shared memory.
Fix it by cleaning up unix_key and nativeKeyFile if shmget() call in
attach() fails.

The attach() -> create() sequence was not covered by unit-tests in
qtbase, but this approach is used inside QSharedImageLoader.
It turns out that 02c42b26e1 broke this
usecase for legacy mode, and the create() triggered an assertion
in QSharedMemorySystemV::updateNativeKeyFile(). Fix it by clearing
the nativeKeyFile if ftok() call in QSharedMemorySystemV::handle()
fails().
Add unit-tests for the attach() -> create() scenario.
These tests revealed that this scenario fails also in non-legacy mode
for SystemV, so add QEXPECT_FAIL for these cases for now. This will
be addressed in a separate patch.

The legacy mode was using the new nativeKey to create a semaphore.
As a result, on macOS the name of the semaphore key file was the same
as the name of the shared memory key file.
This lead to a situation when the file was mistakenly deleted when
destroying any instance of the shared memory, not only the one that
created it.
Fix it by using QSystemSemaphore::legacyNativeKey() in legacy mode.
Add a test to verify that we cannot re-create a shared memory with the
same key. The test was failing on macOS without the fix.

Add the boilerplate standalone test prelude to each test, so that they
can be opened with an IDE without the qt-cmake-standalone-test script,
but directly with qt-cmake or cmake.
Boilerplate was added using the following scripts:

Manual adjustments were made where the code was inserted in the wrong

If a previous test in the same process or previously leaked a shared
memory or semaphore handle, tests could fail and cascade down. They
could also interfere with one another. So prevent this issue by
assigning a monotonically-increasing identifier per test function or row
tested and improving how we clean up those we did create.
This shows we need the API to explicitly clean up.
