refactor(ivy): update ɵɵtextBinding to not take index (#30792)

- Splits core functionality off into a shared internal function
- ɵɵtextBinding will no longer require an index
- Alters the compiler to stop generating an index argument for the instruction
- Updates tests
- Updates some usage of ɵɵtextBinding in i18n to use the helper function instead

PR Close #30792
