[clang][sema] Call expressions are constructed for undeduced deleted functions (#208488)

The deleted function path of overload resolution always constructed a CallExpr node
for the called function even if the function could not be deduced.
This case is handled in other paths by DiagnoseUseOfDecl which does perform that
test. The delete path cannot use that path though, as DiagnoseUseOfDecl rejects
deleted functions, and the entire point of this code is to permit the continued
evaluation of code even if the resolved function was deleted.

To fix this we now manually check for a complete type before continuing to construct
a potentially bogus CallExpr.
