The DirectWrite "bold simulation" has poor results with some fonts;
we already disable it by default for webfonts, to avoid rendering
issues.

As it also works poorly with some of the component layers in Segoe UI
Emoji, let's disable it for COLR fonts as well.

Bug 1868737 - Allow minimal gfx features by default for uncertain configurations. r=jrmuizel,perftest-reviewers,kshampur a=RyanVM

Some features such as the GPU process (except on Android), backdrop
filter (because it always works with Software WebRender), ANGLE (because
it is generally good) and out of process WebGL (we generally want to
remote WebGL for sandboxing purposes) are special, and should not be
disabled simply because we are uncertain about our configuration. In
these situations, disable most features, but keep these enabled by
default.

Bug 1870159 - Use a different string for empty driver versions. r=aosmond,win-reviewers,mhowell a=RyanVM

This lets us distinguish parse failures from empty versions in
telemetry.

The bug occurs because some abspos children are split, but not being reflowed
again in the last column balancing reflow where the available block-size of the
last column might be unconstrained.

This patch makes the callers utilizing `ReflowInput::ShouldReflowAllKids()`
always reflow in the last column balancing reflow to ensure the correctness of
the layout.

Note: the `mIsInLastColumnBalancingReflow` flag is inheriting from parent to
child reflow input, but it will stop at the nested `nsColumnSetFrame` because
the nested one will create its own `ReflowConfig::mIsLastBalancingReflow` and
assign that flag when creating the reflow input for the children.

Bug 1878182 - Instantiate Cairo scaled font for ScaledFontBase::GetPathForGlyphs. r=jfkthameApproved for 123 beta 8, thanks. a=pascalc

This bug likely dates back to bug 1584268, which makes it so that Cairo scaled fonts must be
instantiated on demand for their first use. It seems like some StrokeGlyphs machinery got
overlooked and somehow never caused a problem till now.

* the certificates were regenerated using `./mach generate-test-certs`
* the build/pgo/certs/ changes were made using
  `./mach python build/pgo/genpgocert.py`
* the zip files in security/manager/ssl/tests/unit/test_signed_apps/ were
  updated per the directions in the corresponding moz.build file
* security/manager/ssl/tests/unit/test_cert_override_read.js needed manual
  updating

These certificates and other test artifacts will now expire in 2025.

distutils is no longer available in Python 3.12, which means we cannot
require it on bootstrap, otherwise we cannot bootstrap from Py 3.12.

We already require setuptools as part of mach's requirements, so it's
fine to depend on setuptools elsewhere.
