testlib: fix data races on the current test's identifiers

qDebug() and friends reach the loggers from whatever thread called them,
so generateTestIdentifier() and QXmlTestLogger::addMessage() read the
current test function and data tags while the main thread moves on to
the next row. Those strings don't outlive the test function either:
currentTestFunc points into a QByteArray local to invokeTest(), and the
QTestData rows belong to a QTestTable local to it. So a logging thread
could read freed memory, or a pointer that turned null between the check
and the dereference.

Locking the accessors doesn't help: they hand out a raw const char* that
the caller still uses after unlocking. Keep our own copies of the four
strings instead, refreshed by the main thread whenever the identifiers
change, and hand them out only under a mutex, via
QTestResult::IdentifierLocker.

Fixes the races TSan reports in tst_http2::goaway().

tst_QGraphicsView: Widen the scrollBarRanges test view to 400px

scrollBarRanges resizes the view to a 250x100 top-level window and
compares the scroll bar ranges against values derived from that width.
On OHOS the minimum window size (320x72 vp) is enforced, so the window
is widened past the requested 250px, the viewport no longer matches the
width the expected ranges were computed from, and the scroll bar range
comparisons fail.

Increase viewWidth from 250 to 400, above the enforced minimum. Every
expected value is relative to viewWidth/viewHeight, so widening it keeps
the comparisons consistent on all platforms. viewHeight, at 100, is
already above the minimum and is left unchanged.
