Introduce `GenericSelectionExpr::Association` which wraps an association
expression and its `TypeSourceInfo`. Add the boilerplate necessary to use
ranges of `Associations`.

Additionally pack `GenericSelectionExpr` by tail-allocating the array of
selection expressions and `TypeSourceInfo`.

Note that this is just a draft following D56959 <https://reviews.llvm.org/D56959>.
