With newer standards the readability of template heavy code can be improved a lot by using a form with trailing _t for ::type and _v for ::value respectively. Especially for ::type it also makes the additional typename before the trait dispensable. This PR combines multiple commits that modernize the traits, starting with what clang-tidy could achieve while analyzing test files and continuing by regex replaces with few manual corrections. While it does not guarantee that all current occurrences are modernized, it moves the codebase considerably into the modern direction. Note that also before this PR both notations were used, so missing a few should be acceptable.
