This commit removes the runtime flags and related code for the
scriptminsize and scriptsizemultiplier, which have been disabled by
default for a while. The hardcoded default values
kMathMLDefaultScriptSizeMultiplier and kMathMLDefaultScriptMinSizePt
are still used in some places and are preserved for now.

In MathML Core, the recommendation is to directly use the proper
character from the Mathematical Alphanumeric Symbols instead of the
mathvariant attribute. The exception is for automatic italicization on
single-char `<mi>` element. This is implemented via a new text-transform
value "math-auto" [1] which is the default on the `<mi>` element. The
mathvariant attribute is now restricted to that element and to value
"normal" in order to force upright text instead [2]. This CL implements
this restriction together with that new text-transform value under the
mathml.legacy_mathvariant_attribute.disabled flag.
Some legacy MathML cases where math-auto alone does not work are
still handled via MathMLTextRunFactory.

In order to perform basic mathvariant transforms (italic, bold, and
bold-italic) on systems that don't provide the proper characters from
the Mathematical Alphanumeric Symbols block, a fallback using font
italic/bold style was implemented in Gecko. Nowadays, several fonts
provide glyphs for these characters and are pre-installed on Desktop:
- Cambria Math (pre-installed on Windows Vista and higher)
- STIX General (pre-installed from OS X Lion to macOS Monterey)
- STIX Two Math (pre-installed on macOS Ventura and higher)
- DejaVu (pre-installed on the most popular Linux distributions)
This commit put the fallback under a preference that is disabled by
default on Desktop. It is still required on Android because the
default fonts are not enough.

This is a follow-up of 1788645, removing the font weight/style reset in
MathMLTextRunFactory when the mathvariant transform is not none. A WPT
test for mathvariant="double-struck" is added to exercise this case.

Now that cbindgen and rust support const generics, it seems more simple.
This centralizes all the relevant font constants etc in rust and avoids
conversions when going from rust to C++ and vice versa.

To look up/instantiate platform fonts based on CSS font properties, we create a gfxFontGroup from an nsFont and other attributes; this is currently cached in an nsFontCache attached to the nsDeviceContext.
However, this assumes that the mapping to platform fonts will be the same for all documents using the given device context. In a world where visibility of platform fonts to the page may be restricted, and may depend on the individual document (e.g. if the user disables tracking protection for a particular site), the mapping represented by nsFontCache may vary, and determining how to resolve a given font request will need access to the requesting document in order to know what visibility it is allowed.
To support this, this patch moves the nsFontCache from nsDeviceContext to nsPresContext. In itself, this should cause no visible change in behavior, but it provides a basis for the patches that will follow in bug 1715501.
It's likely that this will have some effects on individual performance tests, depending on the exact content and sequencing of page loads, because of changed caching behavior. E.g. having a per-presContext cache may sometimes mean that we no longer take advantage of a cached gfxFontGroup that a previously-loaded page created; but on the other hand the caches will tend to be smaller and have faster lookups.
My testing so far suggests that we will see some apparent regressions, alongside some improvements, but that overall there should be little change. I'd like to get this change landed separately, before any of the actual font-visibility behavior changes, so that we can more clearly see and isolate any unexpected effects.

This avoids arbitrary precision loss when computing REM units and so on,
which is particularly important if we ever change the base of our app
units (but useful regardless).

Per the discussion in:

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

This allows us to reduce #include usage of the massive gfxFont.h header,
and keeps this specialized kind of TextRange struct local to where it's used.

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.
