Highlights of the release

Warn when an explicit using argument clause with defaults shadows given in the scope #23559

If a call supplies any using argument explicitly, given search is not performed for the remaining params in that clause. If a remaining param has a default, that default is used, even if a compatible given is in scope. This behaviour could have been confusing for users and lead to unexpected problems at runtime. The compiler now reports a warning when default argument would be used instead of given defined in the scope.

def f(using x: X, y: Y = defaultY) = ???
given Y = ???
f(using x = X()) // warns: y = defaultY

This change also adds new flag -Wrecurse-with-default to emit warning when a method calls itself using a default argument instead of forwarding the current value
