fix: Fix an issue where SD L2Cap tx queue would overflow
If more L2Cap packets are queued than allocated at SoftDevice initialization
time (ble_l2cap_conn_cfg_t::tx_queue_size), SoftDevice will throw an error. This
patch updates Rust L2Cap wrapper Channel::tx to async yield
if the tx queue is full.
