Out of curiosity, what is the performance gain?

@lpinca I didn't run a benchmark (or can run a benchmark on CI, because the benchmark CI is down), but knowing the implementation (which is SIMD based), there should be a gain. (Long story short: I don't know lol)

@lpinca I don't think we need to be terribly worried about performance properties of the inspector code either way 🙂 It's a nice step towards making the inspector work in --without-intl mode, I think that would be the main benefit here (assuming that that is possible on the V8 side).

Maybe the PR could be re-framed then by dropping the performance tag and changing the commit message to be something like src: replace icu with simdutf for char counts ?

I am fine with changing the commit name and removing a label, but I would kindly ask to do this through the CLI while merging so that we don't have to go through the flaky tests one more time. I appreciate if you can remove the commit-queue label and merge this when the time comes @mscdex

Many tests started failing on ARM64 Windows after migrating from icu to
simdutf. This change reverts those changes for the problematic platform.
