Restore 'parameters' and 'typeParameters' for ParameterElementImpl.

This partially reverts https://dart-review.googlesource.com/c/sdk/+/5000
which was done during moving toward integration with Kernel, which
we don't do anymore.

With summary2 the FunctionType of a function type parameter is purely
synthetic, without its original element. However parameters in
function typed parameters still exist as nodes, so they must have
elements.
