FFieldPathProperty applies redirects on ImportText_Internal, automatically redirecting FFieldPath saved in string format for blueprint graph pins.
FGameplayAttribute applies redirects after deserializing unredirected value and fixes up derived properties, for UObject based assets with FGameplayAttribute properties.
UAttributeSet subclass renaming and adding ClassRedirect works now. Previously, FGameplayAttribute pins would show correct value in blueprint graphs but use incorrect value at runtime.
FGameplayAttribute renaming and adding PropertyRedirect works now. Previously, FGameplayAttribute fields in blueprint assets would break (null out), in addition to blueprint graphs using undirected value at runtime.

Takeaways. Try to use "friend" on functions/operators that are frequently overloaded EXCEPT if they are in a templated type that is frequently instantiated. So do not put friends in TMap, TSet, TObjectPtr etc, this will slow down compile times. There is a break-even somewhere and hard to tell where it is but taking a class that is templatized on character type probably don't matter either way and then it is nicer to use a friend since that simplies error messages when compiler can't resolve functions/operators.
If it is possible to use member functions instead of friend that is the best option in terms of compile time performance. With c++20 you only have to write operator==(Foo, Bar) and the compiler will automatically provide operator==(Bar, Foo), operator!=(Foo, Bar) and operator!=(Bar, Foo).
Changes in this changelist involes
* Making operator<< friends in non-template types and not friends in template types
* Making operator==/!= members where possible and if not possible moved out if type is a frequently instantiated templated type.

Moved GetTypeHash function to be hidden friend instead of put directly in global namespace.
Note that the function/operator needs to be fully inlined in the type or placed in the cpp. If the function is added as friend but then implemented outside the type then hidden friend optimization won't work.
This should improve compile time somewhat according to msvc devs.
