Make it possible to deprecate all variants of a ParseField with no replacement (#53722) 

Sometimes we want to deprecate and remove a ParseField entirely, without replacement;
for example, the various places where we specify a _type field in 7x. Currently we can
tell users only that a particular field name should not be used, and that another name should
be used in its place. This commit adds the ability to say that a field should not be used at
all.
