src: migrate String::Value to String::ValueView

[RedYetiDev]

Fixes #54417
Ref: #55452

v8::String::Value is deprecated, so this PR replaces it with v8::String::ValueView

[RedYetiDev]

I've added needs-benchmark-ci PR that need a benchmark CI run. in case this slows / speeds things up / down

I've also added needs-citgm PRs that need a CITGM CI run. as a "just-in-case", as this modifies very important code (E.G. Buffer's IndexOf), and it would be unfortunate if it breaks something we were unaware of.
