After #33577, `get_outer_sizes_from_style()` is only used for column and
cell measures. For these it's expected to ignore sizing keywords like
`min-content`, so rename the function to `get_outer_sizes_for_measurement()`.
Additionally, both callers need the percentage contribution, so include
it in the returned tuple.

Instead of a blocking a layout thread on the generation of WebRender
`FontKey`s and `FontInstanceKey`s, generate the keys ahead of time and
send the font data to WebRender asynchronously. This has the benefit of
allowing use of the font much more quickly in layout, though blocking
display list sending itself on the font data upload.
In order to make this work for web fonts, `FontContext` now asks the
`SystemFontService` for a `FontKey`s and `FontInstanceKey`s for new web
fonts. This should happen much more quickly as the `SystemFontService`
is only blocking in order to load system fonts into memory now. In
practice this still drops layout thread blocking to fractions of a
millisecond instead of multiple milliseconds as before.
In addition, ensure that we don't send font data or generate keys for
fonts that are used in layout but never added to display lists. This
should help to reduce memory usage and increase performance.
Performance of this change was verified by putting a microbenchmark
around `FontContext::create_font` which is what triggered font key
generation.

This adds a 'is_fetchable()' method on the ProtocolHandler trait that is then used in the fetch code.
The 'data:' protocol handler is updated to return true instead of hardcoding the scheme comparison, as well
as the 'urlinfo:' handler since it's just a testing one.

CAPMIN is the largest min-content contribution of the table captions.
In Servo, the standard way to compute min/max-content contributions is
`outer_inline_content_sizes()`, so just use that instead of reinventing
the wheel.
This also fixes cyclic percentages to resolve consistently with normal
block boxes.

This will allow callers to start obeying `min-content`, `max-content`,
`fit-content` and `stretch` in follow-up patches.
The old functionality is kept as deprecated methods that we should
eventually remove.
This patch has very little impact on the existing behavior, just some
very minimal implementation of the keywords for css tables.
This also overhauls fixed-layout-2.html since:
- It had code that wasn't doing anything
- It had wrong expecations in prose
- The logic seemed broken in general
- All browsers were failing one testcase

Move `--flavor` to a new "Packaging options" group, so that
we can only apply the flavor option to the commands that support it.

* Fix table track constraindness
Only as size that isn't `auto` and doesn't contain percentages can constrain
a table track (https://drafts.csswg.org/css-tables/#constrainedness).
However, in a bunch of cases we were only checking for `auto`.
Also, we were allowing the inline-size of a cell to constrain both its
column and row. Using the block-size of the row makes more sense.
The spec doesn't define constrainedness for rows, though.

We have improved the logic for computing intrinsic sizes, and apparently
we are no longer getting a `ContentSizes` whose `min_content` is greater
than the `max_content`.

Support different product flavors (e.g. with different signing
configurations) by supporting --flavor on ohos.
The flavor influences the package path for OH packages, so

This is done by no longer forwarding compositor-bound messages through
SystemFontService and making `FontContext` non-generic:
- Messages from the `FontContext` to the `Compositor` no longer need to be
forwarded through the `SystemFontService`. Instead send these messages
directly through the script IPC channel to the `Compositor`.
- Instead of adding a mock `SystemFontServiceProxy`, simply implement a
mock `SystemFontService` on the other side of an IPC channel in the
`font_context` unit test. This allows making `FontContext`
non-generic, greatly simplifying the code. The extra complexity moves
into the unit test.
These changes necessitate adding a new kind of `FontIdentifier`,
`FontIdentifier::Mock` due to the fact that local fonts have
platform-specific identifiers. This avoids having to pretend like the
system font service can have web fonts -- which was always a bit of a
hack.
These two changes are combined into one PR because they both require
extensive and similar chages in the font_context unit test which
dependended on the details of both of them.

This makes the determination of whether or not to use fast shaping
platform independent. Previously it was less stringent for Windows,
leading to using it in cases where a font had a GSUB or GPOS table --
which broke proper shaping.
In addition, the test is made platform independent and expanded to be
more complete.
Finally, comments are added indicating that "fast shaping" will be
removed.

This changes modifes the way that font data is sent over IPC channels.
Instead of serializing the data or sending it via IPC byte senders, font
data is copied into shared memory and a copy of the handle is sent over
the channel.
There is also the idea of sending the file handle of the on disk data of
system fonts. This could be implemented as a further followup once there
is an abstraction in `ipc-channel` over file handles.
To accomplish this, a `FontData` abstraction is added, which also allows
caching an in-memory shared `Arc<Vec<u8>>` version of the data (neeeded
by some APIs). This could also be a place for caching font tables in the
future.
Finally, the `FontCacheThread` is renamed to the `SystemFontService`
while the proxy for this is now named `SystemFontServiceProxy`.
