QWindows11Style: Honor custom text color in palette for TabBarTabLabel

Custom text color set in a palette was not honored in the
QWindows11Style for the CE_TabBarTabLabel, this patch checks, if a
custom color was set in the palette and uses the custom color instead of
the WinUI3 colors.

rhi: Fix out-of-bounds read when loading a corrupt pipeline cache blob

The OpenGL and D3D11 backends serialize their own list of entries into
the pipeline cache blob and walk it again in setPipelineCacheData(),
trusting the entry count and the per-entry length prefixes while
validating only the total size. A truncated or crafted blob therefore
read past the end of the data, with the over-read bytes ending up in the
cache, and with OpenGL also handed to glProgramBinary() later on.

Add a bounds-checked reader and use it in both backends, ignoring the
blob on the first inconsistency, just like for a version mismatch.

Also evaluate the blob size check in 64-bit so that
dataOffset + header.dataSize does not overflow on 32 bit archs. That
change is relevant for the Vulkan and Metal backends as well.

Add some autotests.

value. Theoretical for well-formed content since we do not
support > 4 GB (sometimes 2 GB) content anyway. Relevant

Windows QPA: Restore parent cursor after hiding a modal dialog

When a widget has a custom cursor (e.g. WaitCursor) and a modal dialog
is shown and then closed, the parent widget's cursor is not restored.

Fix by calling applyCursor() on the parent's platform window after
hiding a modal window. This bypasses the cursor change optimizations
that would otherwise skip the update.

Windows 11 style: do not round the corners of fullscreen windows

A fullscreen window with rounded corners does not cover the whole
screen. Set the corner preference to DWMWCP_DEFAULT when a window is
fullscreen and round the corners again when it leaves fullscreen.
Handle QEvent::WindowStateChange so the corners are also updated when
the window state changes after the window is shown.

Add an auto test that checks the corner preference of a fullscreen
window.

AndroidTestRunner: add tst_androidtestrunner

A Python orchestrator under tests/auto/util/androidtestrunner/
drives the host androidtestrunner against a testapp on a device.
The testapp builds as MANUAL so it is not a ctest entry itself.

CommandLineTests exercise the parser without a device:

- help and case sensitivity
- --apk and --aab conflicts
- bare CI -o forms
- --verbose
- --timeout (killing a hanging adb)
- value-taking option at end of argv ("Option --apk requires a value")
- manifest fallback discovery, explicit override, and non-existent path
- --bundletool path existence check
- --activity option is accepted
- INSTALL_ROOT scoping to the GNU-make family
- --skip-install-root override
- missing APK detection
- device discovery and serial-pin paths

DeviceRunTests run against a real device:

- scenario-controlled exits (pass / fail / skip / crash / qFatal)
- function and data-tag selection
- QT_ and QTEST_ env-var forwarding with spaces
- every -o output format
- ndk-stack symbolication with default and explicit --ndk-stack,
  missing path, non-zero exit, and non-executable file
- ANR detection
- AAB install + run
- per-serial QLockFile recovery and concurrent same-serial serialise
- --show-logcat
- --pre-test-adb-command
- SIGINT cleanup

The class auto-skips when no device is attached and tearDown
uninstalls the testapp. ANR and SIGINT cases poll dumpsys for
the foreground focus rather than relying on a fixed sleep, and
the concurrent lock test staggers the second runner via a
pre-test adb sleep so it is deterministically the one that waits.

fake_adb and fake_make context managers back the device-free tests.

Align parsing of time-zone long forms with old parser

Amends commit 0923c473e20d66e0fb5e12a5fef7683bd979d120 (6.12).
I'd failed to notice that the old parser accepted the LocalTime name
supplied by the system (from tzname[] or equivalent) for the
full-length tttt zone format as well as the generic t format.
Tweak the parsing of the old Qt format strings to take that into
account.

Thanks to Albert Astals Cid for catching this with a KDE test.

Avoid overflow in QJalaliCalendar::dateToJulianDay()

If year is close to INT_MIN, subtracting 474 from it will underflow.
However, all we need is the quotient and remainder of the result of
that subtraction, which we can obtain without overflow by rearranging
the arithmetic. Credit to OSS-Fuzz (issue 522858568) for finding it.

The computation of c = qDiv<cycleYears>(y); and then subtracting c *
cycleYears from y was equivalent to computing qDivMod<cycleYears>(y)
and using its quotient and remainder. As y is just year minus an
offset, we can qDivMod<cycleYears>(year) directly and then adjust its
result by the relevant offset, transfering cycleYears from quotient to
remainder first if remainder was too low. Since the quotient's range
of possible values is well within that of int (by a factor of
cycleYears) its adjustment is in no danger of underflow; and
remainder's range is likewise safely in the range from zero to (just
before) cycleYears, so safe.

Add tests of QDateTime and the new temporal parser based on the fuzzer
test-data for the former that found this. The latter made the failure
reachable by supporting years with more than 4 digits, and is new in
6.12, so these tests won't work in older versions, but the overflow
fix is still valid there.

tst_QMetaType: check QMetaType().isSameType() everywhere

The old code only had is as a compile-time only check, guarded by some
#ifdefs which are clearly not met on all supported platforms.

Add the test also as a runtime test. For platforms where the
static_assert is seen, this might be removed as dead code by the
optimizer, but we have checked it at compile-time already. And for the
others, it will perform the check, albeit at runtime.

tst_QMetaType: unbreak ubsan build

Ubsan builds complained that QMetaType().isSameType<T>() wasn't a
constant expression for several types (even in C++2c builds). This is
a recurring problem: ubsan seems to insert checks that are not
constexpr'able; we have the same issue in tst_QByteArrayView, so apply
the same solution: remove the check for ubsan builds.

QLocalTime: remove unneeded narrowing conversion

The old code first assigned epoch.remainder (a qint64 variable) to an
int variable, just to widen it again to qint64 for the call to
secondsAndMillisOverflow(). In particular, it Q_ASSERTed the range
_after_ narrowing, so potentially misses actual out-of-range cases.

Use auto to avoid the narrowing.
