  [mlir][quant] Print actual quant storage type when signed (#187300)

Without the fix, bytecode serialization roundtrip breaks for types that
don't have custom bytecode serializers and contain quant types, since
the fallback mechanism prints the type and the quant printer coerces
signed to signless types. E.g. `!custom<!quant.uniform<ui8:f32, 0.1>>`
will print as `u8` when serializing and later be created as a signless
`i8` when deserializing.
