1f6cac0da9 Make WASM export names different across modules
The export name is now ${TARGET_NAME}Entry. This can also be overridden
by using QT_WASM_EXPORT_NAME, both in CMake and qmake

b2093aad39 Add keyboard input testcase to the QWasmWindow test
The test checks whether correct windows get correct keyboard input,
having been activated with mouse clicks.

Also fixes the event propagation error found. Key events would propagate
to parent windows, which is something that should not happen with
window managers.

fc4fca6d9d Support child windows on WASM
Setting parents for WASM platform windows is now supported. This means
that windows now reside in a hierarchical window tree, with the screen
and individual windows being nodes (QWasmWindowTreeNode), each
maintaining their own child window stack.

The divs backing windows are properly reparented in response to Qt
window parent changes, so that the html structure reflects what is
happening in Qt.

a1704ee6aa Correctly focus WASM windows on show
Since first requestActivate may happen before the window div is
actually displayed on-screen, we need to sync Qt's activation state
with DOM as soon as DOM element becomes visible. Focusing an
invisible element is impossible.

b9491daad0 Modernize the qtloader
This is a minimal version of qtloader. The load function accepts
the same arguments as emscripten runtime with a few additions:
- qt.environment
- qt.onExit
- qt.containerElements
- qt.fontDpi
- qt.onLoaded
- qt.entryFunction

State handling has been removed in favor of making the load async
(assume loading when the promise is live).

Public APIs getting crashed status, exit text and code have been
refactored into the new qt.onExit event fed to load. No need for
keeping the state in the loader.

The loader is integration-tested. A test module with test APIs
has been created as a test harness.

The runtime APIs exposed by Qt (font dpi and screen API) are handled
by the qtloader seamlessly.

1dd8b5ceec rhi: Make it a QPA-style private but semi-public API
qrhi.h, qshader.h, qshaderdescription.h (and qshaderbaker.h from
shadertools; done separately) become "RHI APIs", following the concept
of QPA APIs.

Mirror completely what is done for QPA headers, but using the "rhi"
prefix for the headers. This involves updating syncqt to handle the
new category of headers. (a note on the regex: matching everything
starting with "qrhi" is not acceptable due to incorrectly matching
existing and future headers, hence specifying the four header names
explicitly)

There is going to be one difference to QPA: the documentation for
everything RHI is going to be public and part of the regular docs, not
hidden with \internal.

In addition to the header renaming and adding the comments and
documentation notes and warnings, there is one significant change
here: there is no longer a need to do API-specific includes, such as
qrhid3d11[_p].h, qrhivulkan[_p].h, etc. These are simply merged into a
single header that is then included from qrhi.h. This means that users
within Qt, and any future applications can just do #include
<rhi/qrhi.h> (or rhi/qshader.h if the QRhi stuff is not relevant), no
other headers are needed.

There are no changes to functionality in this patch. Only the
documentation is expanded, quite a lot, to eliminate all qdoc warnings
and make the generated API docs complete. An example, with a quite
extensive doc page is added as well.

fb8832de9c Make the promises js-less using a newly introduced thunk pool
Since we cannot rely on the clients specifying a suitable CSP that will
not forbid execution of js injections, we have to refrain from using
any explicit <script> elements. To keep the promise system working, a
thunk pool was introduced which keeps track of a limited pool of promise
callback exports. In case the resources are busy, pending calls are
enqueued. This works since the JS Promise.then/catch/finally always fire,
even on ready/failed promises.
As the situation of full thunk pool allocation is unlikely to happen
en masse IRL, the solution should not adversely affect the performance.
Heavy unit tests were created to confirm the solution works as expected.

e3b3c77d0e wasm: Improve wheel event handling
Always invert scroll deltas. This is what the code did
before, expect for on non-Safari macOS. There is no
need any "smart" code here: correct deltas are provided
by the native API regardless of macOS scroll direction
setting.

Reading webkitDirectionInvertedFromDevice is still useful
for certain use cases, such as 3D scene zooming or spinbox
value change, where upwards motion on the trackpad should
always correspond to "increment" regardless of scroll direction.
Propagate this to Qt using one of the handleWheelEvent()
overloads

Finally, we were sending pixel deltas as angle deltas;
fix by sending pixel deltas as well, but keep existing
angle delta behavior for compatibility.

f0be152896 wasm: improve clipboard support
Add support for Clipboard API
Add clipboard manual test

Also includes these fixes:

- improve clipboard use for chrome browser
- make QClipboard::setText work
- html copy and paste
- image copy/paste

Chrome browser supports text, html and png

To use the Clipboard API, apps need to be served from
a secure context (https). There is a fallback in the
case of non secure context (http)

- Firefox requires dom.events.asyncClipboard.read,
dom.events.asyncClipboard.clipboardItem and
dom.events.asyncClipboard.dataTransfer to be
set from about:config, in order to support the
Clipboard API.
