Subject: [PATCH] Defer to TextField in TextFormField docs (#9144)

TextFormField doesn't actually have many properties because it wraps a
TextField. Rather than trying to document all the arguments in the
constructor, we now refer to the docs for TextField, which explain the
parameters in a more readable way.

Fixes #7245
