AndroidTestRunner: parse CLI arguments via QCommandLineParser

Replace the hand-rolled if/else loop and printHelp() with
QCommandLineParser, dropping the parallel help text that had to track
parseOptions() by hand.

A splitOwnAndTestArgs preprocessor inserts -- ahead of the first
unknown arg, so CI wrappers can keep appending QTest's bare CLI
("-o file,xml", "-,txt") without a separator. The set of known
options is derived from what the parser already has. The
preprocessor fails the run early with "Option --<name> requires a
value." when a value-taking flag is the last argv entry, instead
of letting the parser report a less informative "Missing value".

When --aab is given, verify the --bundletool path actually exists
up front so a missing jar surfaces a clear runner-level error
instead of a confusing 'java -jar /no/such.jar' failure later.

Behavioural change: option matching is now case sensitive.

CMake: Fix passing of defines with parentheses for EP examples

Some repo .cmake.conf files have

 set(QT_EXTRA_EXAMPLE_TARGET_DEFINES
     "QT_ENABLE_STRICT_MODE_UP_TO=QT_VERSION_CHECK(6,11,0)"
 )

When building examples as external projects these defines got added
to CMAKE_CXX_FLAGS_INIT and broke the build because of the
un-escaped parentheses, with an error like:

 CMake Error at CMakeTestCXXCompiler.cmake:60 (message):
 The C++ compiler is not able to compile a simple test program.
 /bin/sh: 1: Syntax error: "(" unexpected

Instead of adding the defines to CMAKE_CXX_FLAGS_INIT, the build
system now generates a CMake file that is included in the top-level
project() call of each example project.

The file passes the defines to the compiler via
add_compile_definitions() which ensures proper escaping on the command
line.

CMake/Android: keep the OpenSSL root in CMake path format

The auto-bundled OpenSSL paths go into QT_ANDROID_EXTRA_LIBS,
which the deployment settings writer keeps as is under
QTP0002 NEW. Backslashes in a native Windows OPENSSL_ROOT_DIR
are read as escapes when that JSON is parsed, so
androiddeployqt gets a path that lost its separators:

  External library C:Utilsprebuilt-openssl.../libcrypto_3.so
  does not exist!

Convert the OpenSSL and vcpkg roots on Windows hosts.

androiddeployqt: resolve lib dependencies without ABI suffix

The module dependency XML records every <lib> entry with
an ABI suffix, the way Qt's own Android libraries are built.
Prebuilt libraries in the Qt prefix, such as FFmpeg, keep
their plain name, so the recorded name is not there:

  llvm-readobj: error: '.../libavutil_arm64-v8a.so':
  No such file or directory

Resolve an entry that is not on disk to the other spelling,
and check the architecture of the resolved path. The raw
relative name only worked while it carried a suffix, which
is recognized by name alone, so a plainly named entry was
dropped silently. Also stop absoluteFilePath() from prefixing
an absolute path.

CMake/Android: don't mangle XML lib dependency paths

The XML writer replaced every ".so" in a path, so an absolute
entry, one that already had the ABI suffix, or a ".so" inside
a directory name came out mangled.

Rewrite only a trailing ".so", and leave an absolute or an
already suffixed entry alone. No current entry hits any of
those, so the generated XML is unchanged.

HTML export: emit the title attribute for tool tips

QTextHtmlParser reads the "title" attribute of an <a> element into
QTextCharFormat::toolTip() (the TextToolTip property), and that tool tip is
shown on hover by the widgets (QWidgetTextControl::showToolTip) as well as
by Qt Quick's Text and TextEdit hoveredToolTip property. But the HTML
exporter wrote only the href, so a link tool tip was silently dropped by
toHtml() and did not round-trip - even though the Markdown writer already
preserves it, and images already export their title.

Any HTML tag can have a `title` attribute. We now emit it as part of a
<a> <img> or <span> tag when the char format specifies a tooltip.
For links and images, this round-trips consistently between HTML and
Markdown import/export. (Markdown doesn't have a way to specify titled
spans though.)
