[analyzer] Implement path notes for temporary destructors.

Temporary destructors fire at the end of the full-expression. It is reasonable
to attach the path note for entering/leaving the temporary destructor to its
CXXBindTemporaryExpr. This would not affect lifetime-extended temporaries with
their automatic destructors which aren't temporary destructors.

The path note may be confusing in the case of destructors after elidable copy
constructors.
