Replace a bisect with a single multiplication when calling
screen_get_dpi() in Javascript
Tested the value of
window.matchMedia(`(resolution:${(window.devicePixelRatio*96).toFixed(100)}dpi)`).matches
which is true except for values that cause a lot of rounding errors
(e.g. dpr : 0.3 => resolution: 28.799999999999997dpi)
Even in these cases the value matches the result of the previous
`findDPI()` method.

Used default value before, i.e. "same-origin", now uses "include" (i.e.
include for cross-origin if cross-origin is allowed).

Allows detecting when a new version of the progressive web app service
worker is waiting (i.e. an update is pending), along a function to force
the update and reload all clients.
Use an offline first approach, where we prefer the cached version over
the network one.
This forces games using PWA to always re-export the project and not just
the PCK, so that the service worker version gets updated correctly, and
the end-user cache is correctly cleared on update.
The code to populate the input data for WebAssembly was incorrectly
overriding values when multiple touches were present due to wrong
indexing.

The "webgl/webgl2.h" include provides that function, but it's not
available in emscripten versions < 2.0.17 .
Since we need to support emscripten 1.39.9 (mono builds), this commit
adds a JS function in library_godot_display.js as a compatibility layer
for it, and implement glGetBufferSubData by funneling the call to that
function (so we don't have name collisions JS-side with recent emcc).
All those hacks are now moved to the platform directory instead of being
ifdefs inside the drivers implementations.
This actually makes sense(?), when running inside an iframe the active
element might be our canvas, while the iframe itself is not active in
the parent window. Since we consume the event, the iframe does not get
focused in Firefox (but does in Chromium-based browsers), so we must
always call focus to handle such occasions.

In some conditions the events might be generated even when the `gamepad`
object is not accessible due to Security Context requirements.
This commit adds a check to avoid firing the handler in those cases.

It used an old vendored version of acorn.js which seems to choke on this
trailing comma. This is not a problem for more recent Emscripten versions.
We disable the `comma-dangle` check in ESLint to prevent this issue.

Performances are not great in general, bad on Firefox, on Chrome, well,
it's an improvement compared to the way they broke ScriptProcessorNode.
I'm actually surprised this works, it involves so many allocations, but
there's no way around it when SharedArrayBuffer is not available :(.
Browsers doesn't really like forcing the mix rate, e.g. Firefox does not
allow input (microphone) if the mix rate is not the default one, Chrom*
will exhibit worse performances, etc.
We were using `Content-Length` from the server when `Content-Encoding`
was not set (i.e. response was not compressed).
Sadly, in CORS requests accessing headers is restricted, and while
`Content-Length` is enabled by default, `Content-Encoding` is not.
This results in the impossibility of knowing if the content was
compressed, unless the server explicitly enabled the encoding header
via `Access-Control-Expose-Headers`.
To keep maximum compatibility we must disable `body_size` completely.

Promise chaining the emscripten module `then` function breaks it badly,
causing an infinite loop.
I'm unsure about the source of the issue, but most likely at this point
is due to the old emscripten version (I remember very old html5 builds
having issue with promise chaining too).
With this commit, we no longer use the module as a promise, and
instantiate it using `Promise` objects directly for compatibility.
(cherry picked from commit ae3c9345cc)
`WebAssembly.instantiateStreaming` requires the mime-type to be
`application/wasm`, but some servers (including most debug servers) do
not provide the content-type header.
This commit forces it via JavaScript, by creating a `Response` object
with the `wasm` content, and explicitly defined `content-type` header.

With a very nice hack, a new hidden configuration option that delays
dropped files removal at exit.
This still leaks while the project manager is running, but will clear
memory as soon as it exits or load something.
(reminder, dropped files are reguarly removed after the signal is
emitted specifically to avoid leaks, but I prefer hacking the HTML5
config then the project manager).

It used to be updated before the first iteration, causing the
window/viewport size values to be incorrect during the initialization
phase (e.g. during the first `_ready` notification).

Added as an export option "Experimental Virtual Keyboard".
There is no zoom, so text/line edit must be in the top part of the
screen, or it will get hidden by the virtual keyboard.
UTF8/Latin-1 only (I think regular UTF-8 should work out of the box in
4.0 but I can't test it).
It uses an hidden textarea or input, based on the multiline variable,
and only gets activated if the device has a touchscreen.
This could cause problems on devices with both touchscreen and a real
keyboard (although input should still work in general with some minor
focus issues). I'm thinking of a system to detect the first physical
keystroke and disable it in case, but it might do more harm then good,
so it must be well thought.
