Bump the pinned ICU version from 78.2 to 78.3 — the current release — so
the build works on systems that already ship 78.3. And bump our vcpkg
baseline — because 78.3 is newer than our existing baseline. And pin
freetype to 2.13.3 — because the baseline update otherwise pulls in
2.14.3, which has font-rendering changes that break our layout tests.

The algorithm is ported over from Chromium's, which produces very good
results for speech, while being not objectionable for music, especially
in the background.
Other algorithms were tested.
Phase vocoders:
- Bungee
- Signalsmith Stretch
- pvdoneright
All three of these exhibited the usual phase shifting artifacts,
causing speech to sound slightly shifted into the high end. Speech is
the main thing we want to optimize for, so these aren't ideal.
Sonic (TD-PSOLA) performs better than WSOLA for speech, especially at
rates higher than 2x, but makes background sounds/music garbled and
unpleasant. It is still worth considering for speech clarity, and could
be added as an optional feature.
Use libedit's readline-compatible interface for the JavaScript REPL so
line editing, history, and tab completion no longer depend on LibLine.
The REPL keeps its existing multiline input and completion behavior,
but no longer provides LibLine's live syntax highlighting.
Remove the unused LibLine dependency from the wasm utility and delete
the LibLine library from the build now that it has no remaining
consumers.
Our Flatpak builds currently start failing once a commit ID no longer
matches with the commit pointed to by the configured `branch`. This is
becoming pretty annoying for Skia, since the `chrome/mXYZ` branches are
effectively moving targets.
Change the `branch` key in the Flatpak config to `x-branch`, which
removes the constraint and allows Flatpak to work with just the pinned
commit IDs. Change the linter to still use `x-branch` as the reference
to compare with our vcpkg configuration, so we make sure to still keep
things consistent between vcpkg and Flatpak.
The idea is that scripts directly under Meta are meant to be run by
people. Scripts that are only imported or run by other scripts are
moved to a subdirectory.
Note that the IPC lint step can be removed from the CI workflow because
we no longer need a build in order to perform the lint, and IPC linting
is now covered by lint-ci.sh.
