These two platforms are the easiest to get started with - as well as accounting for the great majority
of desktop Firefox users.
This patch is based on the OS vendors' lists of fonts shipped with the current version of each OS.

This replaces and extends the "hidden" flag we currently use on macOS to mark internal system fonts
like .LastResort and .Keyboard that should not be exposed; rather than just a boolean "hidden" flag
we'll have several levels of visibility, some of which the user may opt in to exposing (at the cost
of potentially becoming more fingerprintable).
The current patch assumes three levels besides always-hidden:
Base - fonts that are part of the base OS install and always available
LangPack - fonts that are provided by the OS subject to user's chosen language options
User - user-installed fonts that were not provided by the OS
(This categorization may be subject to revision as we learn more about real-world needs and
configurations.)

The only caller wants CSS pixels, no need to go back and forth.
This is the last dependency on the pres context, I think, from the style system
font code.

This rearranges how synthetic-bold use is determined in the font selection
& rendering code. Previously, we would decide during the font-selection
algorithm whether we need to apply synthetic-bold to the chosen face, and
then pass that decision through the fontgroup (storing it in the FamilyFace
entries of the mFonts array there) down to the actual rendering code that
instantiates fonts from the faces (font entries) we've selected.
That became a problem for variation fonts because in the case of a user
font, we may not have downloaded the resource yet, so we just have a "user
font container" entry, which carries the descriptors from the @font-face
rule and will fetch the actual resource when needed. But in the case of a
@font-face rule without a weight descriptor, we don't actually know at
font-selection time whether the face will support "true" bold (via a
variation axis) or not, so we can't reliably make the right decision about
applying synthetic bold.
So we now defer that decision until we actually instantiate a platform font
object to shape/measure/draw text. At that point, we have the requested
style and we also have the real font resource, so we can easily determine
whether fake-bold is required.
(This patch should not result in any visible behavior change; that will
come in a second patch now that the architecture supports it.)
Add a boolean value in FindFamily() to check if gecko needs to defer the
InitOtherFamilyNames() task into idle queue.
Add a new telemetry data FONTLIST_INITOTHERFAMILYNAMES_NO_DEFERRING for the
execution time of InitOtherFamilyNames() running regularly at main thread
instead of in idle queue.
