Moves talking nullrod claymore init proc into talking nullrod claymore subtype (#94690)

## About The Pull Request

Spellblade/talking isn't a real subtype, it's supposed to be
claymore/talking, and these are causing two extra empty nullrod subtypes
to be added to GLOB.nullrod_variants. Also, it means that the gimmick of
these nullrods don't work at all.

## Why It's Good For The Game

fixes #94491
The talking sword will talk

## Changelog
🆑

fix: Nullrod possessed swords will talk
fix: Nullrod variant selection menu will no longer have three normal
nullrods as options
