Deprecate invalid InputDecoration.collapsed parameters (#152486)

## Description

This PR is a follow up to https://github.com/flutter/flutter/pull/152165#pullrequestreview-2200072459.
It deprecates two parameters that should not have been added (`floatingLabelBehavior` and `floatingLabelAlignment`) to `InputDecoration.collapsed`. Those parameters are related to the floating label but a collapsed input decoration is not supposed to have labels.

For the dart_fix, I created a new fix file and moved some previous fixes to it.
