qapi: Simplify QAPISchemaObjectTypeMember.check()

QAPISchemaObjectTypeMember.check() currently does four things:

1. Compute self.type

2. Accumulate members in all_members

   Only one caller cares: QAPISchemaObjectType.check() uses it to
   compute self.members.  The other callers pass a throw-away
   accumulator.

3. Accumulate a map from names to members in seen

   Only one caller cares: QAPISchemaObjectType.check() uses it to
   compute its local variable seen, for self.variants.check(), which
   uses it to compute self.variants.tag_member from
   self.variants.tag_name.  The other callers pass a throw-away
   accumulator.

4. Check for collisions

   This piggybacks on 3: before adding a new entry, we assert it's new.

   Only one caller cares: QAPISchemaObjectType.check() uses it to
   assert non-variant members don't clash.

Simplify QAPISchemaObjectType.check(): move 2.-4. to
QAPISchemaObjectType.check(), and drop parameters all_members and
seen.
