6d1fa9fa72 [uart] Remove redundant mutex, fix rx_event_task race, optimize event queue 
Remove the FreeRTOS mutex (lock_) that wrapped all ESP-IDF UART driver
calls. A codebase audit confirmed all UART wrapper methods (read_array,
write_array, peek_byte, available, flush) are called exclusively from
the cooperative main loop. The lock was protecting single-threaded code
from itself and added 4 unnecessary semaphore operations per read_array
call on the hot path.

Fix a race condition in rx_event_task_func where uart_flush_input() was
called from a separate FreeRTOS task without taking the lock, racing
with read_array() on the main loop. This could destroy ring buffer data
mid-read, causing data loss. The flush was also unnecessary since the
ESP-IDF driver self-heals the buffer-full condition: uart_read_bytes()
internally calls uart_check_buf_full() which moves stashed FIFO bytes
back into the ring buffer and re-enables RX interrupts.

Move the event queue allocation behind USE_UART_WAKE_LOOP_ON_RX. When
the feature is disabled, uart_driver_install is called with queue_size=0
and uart_queue=NULL (the documented API for skipping the event queue).
This saves ~320 bytes of RAM per UART instance and reduces ISR overhead
since the driver skips xQueueSendFromISR when no queue exists.

Add thread safety documentation to the class and rx_event_task.
