In order to test its parsing and serialization, we expose it but protect
it behind a pref.
Besides, I would like to drop layout.css.aspect-ratio-number.enabled in
the next patch because the spec has been updated. It seems we don't have
to keep this pref and we should always use Number.

--enable-hardware-aec-ns option does nothing so it is deleted too.

Removed "media.navigator.audio.full_duplex" pref
It was related to `MediaEnginePrefs::mFullDuplex` which wasn't used too, so the according code has been removed

Change --wasm-simd to --no-wasm-simd and flip the default for both this
switch and for the about:config flag.
Add testing directives so that we test baseline, ion, and --no-wasm-simd.

- Use xdg-desktop-portal for file dialog picker on Wayland as the native one can't use clipboard.
- Ship widget.use-xdg-desktop-portal env variable to force xdg-desktop-portal for both print dialog and file dialog.

Converts `ui.menu.incremental_search.timeout` to a static pref and replaces macros related to the incremental search timeout with the actual pref, so that they are kept in sync without the need to manually update any macros. The two `.xml` files mentioned in the note were nowhere to be found, so this patch makes the assumption that those do not exist anymore and do not need to be kept in sync.

See https://bugzilla.mozilla.org/show_bug.cgi?id=932410#c2 for the
context for which this pseudo-element was added.
In the previous patch, I had to special-case range appearance because of
this pseudo-class, but that patch makes this pseudo-class completely
redundant, as now all form controls, themed and unthemed, display
outlines, unless the native theme displays a focus indicator on its own.
Remove the special case, and make ranges use outlines like everything
else rather than this bespoke pseudo-element.

Part 1 of this patch enables subpixel AA in more cases when there
are multiple picture cache slices. Because of this, we can enable
extra picture cache slices by default, as a performance win for
the general case.
Users who want to force subpixel AA in more cases, at the cost of
performance can manually set the about:config value called
gfx.webrender.quality.force-subpixel-aa-where-possible.

This patch will do :
- rename the old pref `media.autoplay.enabled.user-gestures-needed` to the new pref `media.autoplay.blocking_policy`
- modify the value of the pref to `int` in order to introduce new policy
- implement new policy in `AutoplayPoliocy`
The advantage of doing so :
- rename the pref to explicitly indicate that it's related the block policy we use
- use the transient user gesture activation as a new policy to replace the old one using the user input, which doesn't work on the async handler
More details :
The old `click-to-play` policy we use is using the user input to determine if the play invocation is called by users or by scripts. But `UserActivation::IsHandlingUserInput()` is buggy which would fail when you call `video.play()` inside an async event handler. So we would like to replace it with the new transient user activation, which would treat the action as an user input if the action is performed within a certain period of time after a user interacts (eg. click) with the page.

In RFP mode, canvas image extraction leads to an all-white image, replace that
with a random (sample 32 bytes of randomness and fill the buffer with that)
'poison pill'. This helps defeat naive fingerprinters by producing a random
image on every try. This feature is toggled using a new, default on, pref
`privacy.resistFingerprinting.randomDataOnCanvasExtract`.
Updated `browser_canvas_fingerprinting_resistance.js` to test this new feature
as well.
Updates and replaces D66308.

The preprocessor does not handle "# ifdef" like the C preprocessor,
and I failed to test this appropriately after restructuring the
#if... clauses. This also reverts fastShutdownStage back to 1, so
we can be confident in the data we collect.
