fix CLAPAudioCfg assertion error

[l1cacheDell]

When inferencing SD3 in Python3.11, with flag --inference_optimize 1 on, the program throws:

ValueError: mutable default <class 'paddlemix.models.audioldm2.clap_module.model.CLAPAudioCfg'> for field audio_cfg is not allowed: use default_factory

Problem lies on: paddlemix/models/audioldm2/clap_module/clap.py

from dataclasses import dataclass

@dataclass
class CLAPConfig:
    embed_dim: int = 1024
    audio_cfg: CLAPAudioCfg = CLAPAudioCfg()
    text_cfg: CLAPTextCfg = CLAPTextCfg()

maybe higher version python will throw this error, get fixed by:

from dataclasses import dataclass, field

@dataclass
class CLAPConfig:
    embed_dim: int = 1024
    audio_cfg: CLAPAudioCfg = field(default_factory=CLAPAudioCfg)
    text_cfg: CLAPTextCfg = field(default_factory=CLAPTextCfg)
