gdma: prevent mutli-channels connect to the same peripheral
1. add check in the gdma driver, to prevent multiple channels connecting to the same peripheral 2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP targets (e.g. esp32c3/s3). We should search for a free one when install async memcpy driver. Closes https://github.com/espressif/esp-idf/issues/10575
