change(bt/ble_log): remove BLE Log UHCI Out module

Delete ble_log_uhci_out.c and its header. Remove the UHCI Out source
from CMakeLists.txt and all BT_BLE_LOG_UHCI_OUT_* Kconfig options.
Remove per-chip BT_LE_CONTROLLER_LOG_UHCI_OUT_ENABLED Kconfig and
all UHCI Out caller references in esp32c5/c6/h2 controller bt.c.
Update ble_log_console README to reference the new BLE Log Module
UART DMA config. The functionality is superseded by the BLE Log
Module's UART DMA peripheral transport.
