V8 now depends on simdutf

[targos]

See https://github.com/nodejs/node-v8/actions/runs/13004555360/job/36269067298#step:6:14229

I disabled the nightly update workflow because I don't have time to fix it in the coming days.

@anonrig Should we try to use the same code as Node.js or build a separate one pinned to the version that V8 uses? I guess this depends on the stability of simdutf's API (we don't want it to break V8 if we update the dep on our side).

V8 needed a hotfix on their side to build node: v8/node@8d26658

[anonrig]

I'm not sure. The APIs are extremely stable but let's hear from @lemire before making a decision here.

@targos @anonrig I definitively recommend dropping simdutf from Node if it is present in v8. I think everyone would agree.

If this causes any problem, @anonrig and myself can help.

nodejs/node-core-utils#903 to include it in V8 updates

[targos]

Ok thanks! The changes were easier than expected. I pushed them to nodejs/node@f5dea6d and nodejs/node@3b72c69.

Note that at this point, it downgrades simdutf in Node.js from version 6.0.3 to 6.0.2.

@targos That's fine. :-)
