8413c06e2e Disable SAFE_HEAP_LOG for wasm
This option completely ruins the output when running test, as it logs
every single safe heap operation. I don't think this detailed logging
is necessary or reasonable in a normal debug build.

66a76a5def wasm: enable mobile native keyboarding
This works on iOS and Android, and Windows with touchscreen.

On Android, we need to listen to the input event
of a hidden text element and synthesize Qt keyboard
events from that in order to get input events into Qt.

On Windows, we need to be more creative about bringing the native
virtual keyboard up.

Because the entire canvas is contenteditable, we need to specify the
inputmode is set to 'none', otherwise the v keyboard pops up
when user clicks anywhere on the canvas. Therefore we set a hidden
element as contenteditable, which pops up keyboard when Qt
needs it for editable widgets. On Android, this is the same
element that is used to proxy the keyboard input.

[ChangeLog][wasm] Add support for native mobile keyboard

663c1b8827 wasm: remove deprecated argument for source maps
-g4 was deprecated in Emscripten 2.0.17, and since we are well past
that version we can safely use -gsource-map instead.

2148e1f0e6 wasm: increase default initial memory
Some apps may need more initial memory when linking, emscripten will
fail with:
wasm-ld: error: initial memory too small

This increases the default initial memory form 16MB to 20MB.

Larger apps might still get this error, in which case
QT_WASM_INITIAL_MEMORY can be set.

6d039a5e76 wasm: enable event dispatcher asyncify support
Misc. fixes, including:

Fix a couple of typos in the JavaScript code. Also, macros-
within-macros don’t work, (without resorting to preprocessor
token pasting), so remove the debug output for now.

Limit the exec() “simulateInfiniteLoop” workaround to
top-level application exec() only. This way, asyncify
can be used for nested QEventLoop::exec() calls. (Emscripten
supports one level of suspend only, so we don’t want
to use that for the top-level exec(), but instead use it
for dialogs and such).

Use the new QEventLoop::ProcessEventsFlag::ApplicationExec
enum value to detect the exec() call type.

53eb44906c wasm: don’t set exit_runtime
Go with Emscripten’s default of not shutting down on
main() exit; this allows for writing main() in such
a way that avoids the exec() workaround.

Existing main() implementations (which do use the exec()
workaround) do not shut down Qt cleanly anyway, so we
gain little by shutting down the Emscripten runtime.

Applications can set this flag if they do want to shut
down on main() exit:
    LFAGS += -s EXIT_RUNTIME=1

7ee4468a18 wasm: enable MODULARIZE option and set EXPORT_NAME
Make Emscripten generate a global constructor function
("createQtAppInstance()") instead of a global javascript
module object.

This enables more fine-grained control over module
instantiation; previously the module object would be
created when the runtime javascript was evaluated, and
the number of emscripten module/instances was limited
to one per page.

Set EXPORT_NAME to “createQtAppInstance” which avoids
collisions with other non-Qt Emscripten modules on
the same page. A further improvement would be to include
the app name in EXPORT_NAME, but this is not done at
this time.

Update the code in qtloader.js to call the constructor
function instead of working on a global module object.
The qtloader.js API is functional before the wasm and
Emscripten modules have been instantiated; store properties
and forward to the Emscripten module when it's created.
