Morten Johan Sørvig 3a6d8df521 Revert "wasm: Specify event targets by CSS selectors; Support emsdk >= 1.39.5"
This reverts commit c6da278271.

This was a 5.15-only change which should not go into 5.14
since it raises the minimum supported emsdk version.

Morten Johan Sørvig c6da278271 wasm: Specify event targets by CSS selectors; Support emsdk >= 1.39.5
DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR is now on by default, which
means that functions like emscripten_set_keydown_callback() now expects
CSS selectors (e.g. "#canvas_id" instead of "canvas_id").

In addition, Module.canvas is no more. Add a deprecation warning in case
someone is setting it and expects Qt to use it. (qtloader.js sets
qtCanvasElements instead).

This bumps the minimum supported emsdk version to 1.39.5.

Alexandra Cherdantseva 0a4c5b5119 wasm: fix redundant string conversions between wasm and JavaScript
Avoid redundant conversions from UTF16 to UTF8 to UTF16 with
help of new class QWasmString static methods:
+ QWasmString::fromQString to convert QString to js string
using js Module.UTF16ToString
+ QWasmString::toQString to convert js string to QString
using js Module.stringToUTF16

Fixed document.getElementById calls for cavasId with unicode characters.

Should use `document.getElementById`.

Morten Johan Sørvig c8c4819b7b wasm: controlled screen destruction
Freeing OpenGL resources requires a current context,
which (on wasm) requires a screen.

Add a destroy() functions to QWasmScreen, QWasmCompositor, QWasmWindow,
and QWasmBackingStore which facilitates OpenGL cleanup before we start
deleting screen objects.

Morten Johan Sørvig 56acf089c7 wasm: support setting the font DPI from JS
We have not really been able to determine what the
default DPI should be, so make it configurable with
API on qtloader.js:

  qtLoader.setFontDpi(72);

Also lowers the default DPI to the standard value of
96 (down from Qt default 100).

Morten Johan Sørvig caa74f16d4 wasm: support rendering to multiple canvases
Qt (via the the qtloader.js API) now supports rendering
to multiple canvases. The application sees each canvas
as a QScreen.

Make qtloader.js support multiple canvases:

  var qtloader = QtLoader({
    canvasElements : [array-of-canvas],
    showCanvas: function() {
      // make canvas(es) visible
    },
 });

The canvases were previously created/returned by showCanvas(),
however this function is called after the Qt app has
been started and adding screens that that point is
too late. (This worked before since there was only one
screen, and no need to connect each screen instance
to specific canvas.)

Remove QWasmScreen, QWasmCompositor, and QWasmEventTranslator
singletons from QWasmIntegration. These are are now
crated per-screen and are owned by the QWasmScreen.
