driver/i2s: support i2s on c3 and s3

Browse Source 
1. Support i2s on esp32c3 and esp32s3
    2. Refactor i2s_config_t to avoid breaking change
    2. Fix a bug that receiving unavailable values from message queue when dma queue has been re-allocted
    4. Support i2s unit test on esp32c3 and esp32s3
