Modernize and fix callback detection

[dalg24]

Refactor/ modernize callback introspection facility. My initial goal was to get rid of Details::AccessTraitsHelper but I decided to split that up.

Fix bug introduced the refactor in #939 that makes that we were not catching errors like

ArborX/test/tstCompileOnlyCallbacks.cpp

Lines 141 to 142 in 1dc256d

	// check_valid_callback<int>(CustomCallbackMissingConstQualifier{},
	// SpatialPredicates{});

))
