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().

QDirEntryInfo: try [[assume]] to fix Coverity UNCAUGHT_EXCEPTION FPs

Coverity keeps complaining about visit()s in this class potentially
throwing std::bad_variant_access, even after we closed the one real
source of valueless_by_exception() (never realized in practice) by
giving QFileInfo a nothrow move constructor
(cf. eb4b67478a1a36c476ad20a90e7d5a3fd080516c), and added explicit
assertions for !valueless_by_exception()
(cf. 8bd5d7ee8f73dc70871f39e15ccaa785a077dcfc).

Based on feedback from StackOverflow¹, try [[assume]] next. Just
Q_PRESUME(valueless_by_exception()) doesn't compile
(-Werrror,-Wassume, because the function has "potential
side-effects"), so store the result in a local variable and check the
variable. That works at least on Clang 21.

Update our copy of FFTW's cycle counter to 3.3.11

FFTW has released a new version, with support for a couple more
platforms. Update the cycle-counter Qt's benchmarking uses from that.

[ChangeLog][QtTest][Third-Party Code] QtTest's benchmarks now use the
cycle-counter code from FFTW version 3.3.11. This adds support for
LoongArch and RISC-V.
