icu4c@75 75.1 (new formula)

[cho-m]

Created with brew bump-formula-pr.

---

Major changes

This release introduces C++17 minimum which impacts various dependents.

Versioning attempt

As reference:

• Previous bump - icu4c 74.2 #153108
• CI runtime: https://github.com/Homebrew/homebrew-core/actions/runs/8007761525/usage (2d 6h Intel macOS, 1d 17hr Linux)

May try versioning approach and test largest dep group to see if it improves anything.

EDIT: The largest connected deps group means at least 42 formulae need to be migrated on macOS (more if including Linux due to libxml2 and other common dependencies).

Sounds like the ICU's minimum C++ standard is now C++17. Can try to force it, but may cause problems with dependents.
