Remove designated initializers

[adamlm]

Summary

Some parts of the code use designated initializers, which is a C++20 addition even though some compilers support it when targeting earlier standards. This codebase targets C++17, so we should remove the designated initializers.

Adhering to ISO C++ guidelines ensures our code is as portable and maintainable as possible.
