Migrate codebase to std::string_view (except z3++.h) (#8266)

Browse source 
* Initial plan

* Update z3 codebase to use std::string_view (except z3++.h)

- Updated params.cpp/h to use string_view internally for parameter descriptions
- Updated trace.h/cpp to accept string_view for trace tag functions
- Updated hash.h/cpp to use string_view for string_hash function
- Updated all callers of string_hash to use string_view
- Properly handled nullptr to empty string_view conversions
- All tests passing

* Add missing string_view includes to headers
