Looking up the BidiClass property via icu_properties is more efficient than the
built-in version provided in unicode-bidi.

This will cause `./mach vendor rust` to pull it into the tree.
Note that actually running `./mach vendor rust` requires the file-size limit in vendor_rust.py
to be temporarily raised (from 100K to 300K is enough) because of large files in the icu_properties
crate. This does not contribute significant bloat to the binary, though, because only actually-used
data ends up in the build.

unicode-bidi more closely follows the UAX#9 recommendations for processing embedding controls
if they're not actually removed from the text; but this is not an actual spec requirement,
so either behavior is acceptable.

Rather than Diplomat-generated, this is hand-written to provide just the functionality needed in intl::Bidi,
to minimize the amount of glue code and ensure a close match to Gecko requirements.

When reloading https://en.wikipedia.org/wiki/Barack_Obama that is used by
browsertime benchmark, `CountGraphemeClusters` is called around 3000 times.
But half calls are that `aText` is empty.
So if we add fast path for empty text, we can avoid a lot of heap allocations
of `ICU4XGraphemeClusterBreakIteratorUtf16`.

When running wikipedia's page by browsertime benchmark, 0.5%-1% calls of
`LineBreaker::ComputeBreakPositions` is that aLength is 1. If this is 1,
we only set SOT break in ICU4X's line segmenter.
So we can add a fast-path for this situation. `ICU4XLineBreakIterator*`
always allocate rust heap, so we can reduce a few heap allocation costs.

This file shows up after running `update-icu4x.sh`. It is part of the downloaded
`icu_capi` crate. We should check it in for completeness even if it is not used.

Although since `icu_capi` uses weak dependency syntax, cargo vendor doesn't
recognize it. So this command will copy unnecessary crates. To avoid it, I
would like to use modified version of icu_capi.
And this has another issue. `icu_capi`'s C++ headers isn't compatible with
clang [*1]. So we need the workaround for it.
ICU4X 1.3 has another change for data provider with `icu_capi`.
From ICU4X 1.3, there are new `icu_*_data` crates to custom data file, instead
of `icu_testdata`. So we have to add each data crate if using `icu_capi`.

The matching behavior implemented in bug 1857742 did not quite follow the spec,
particularly with regard to language *ranges* (as used in the :lang() pseudo)
that are not themselves valid language *tags*.
This updates the LangTagCompare function to more correctly follow the BCP4647
"Extended Filtering" algorithm, and adjusts the relevant WPT tests (originally
from bug 1857742) to reflect the corrected behavior.
