Fix a bug that causes not handling an IDLE line detection interrupt for
some STM chips, e.g. STM32F412. It impacts the async UART
communication - an information that data have been recieved is lost.
The issue occurs when the IDLE flag is set during handling another UART
interrupt, e.g Transmission complete. The ISR calls uart_stm32_err_check
function, which clears the noise error flag with LL_USART_ClearFlag_NE
without any additional checks. Unfortunately, clearing the noise flag
also clears the IDLE flag for some chips(an read to the USART_SR
register followed by a read to the USART_DR register for STM32F412
clears PE, FE, NF, ORE and IDLE flags), hence the ISR is not called
again for the IDLE event. The IDLE flag is no longer set.
Add checking the noise flag before clearing it.

When checking if any UART TX/RX IRQs are pending, the driver should also
consider whether these IRQs are enabled. Or we still get pending status
set even if the related interrupts are disabled.

Fix the driver so that after a call to uart_rx_disable() it does not
allow re-enabling RX until the UART_RX_DISABLED is generated (what
means that the disabling procedure is complete). Otherwise, it is
possible that the RXTO event from the previous RX is handled right
after a new RX is started, and the RX buffer pointer gets corrupted
in the `rx_flush()` function.

Since the macro references `data->async->hw_rx_counting`, it cannot
be called when `data->async` is NULL, and this could happen when the
PM_DEVICE_ACTION_RESUME action was requested for an instance that uses
the interrupt-driven API while for another instance that uses the
asynchronous API the hardware counting of bytes was configured.
Prevent this by calling the macro from a proper `if` block.

Currently, uart_npcx_pm_policy_state_lock* functions are guarded by
CONFIG_UART_INTERRUPT_DRIVEN && CONFIG_PM. However, it is unnecessary to
guard them with CONFIG_UART_INTERRUPT_DRIVEN as the polling mode UART
driver also uses these functions.
This commit removes it and leaves those functions guarded by CONFIG_PM
only.
