This adds the CONFIG_UART_USE_RUNTIME_CONFIGURE guard to
disable the API function pointers if the kconfig is not enabled.
Both .configure and .config_get should only be usable if runtime
(re-)configuration of UART is needed.
Ifdef guards are added to drivers previously lacking this guard.

Both the IRQ API and Asynchronous API support callback.
However, since they are both interrupt driven, having
callbacks on both API would interfere with each other
in almost all cases. So this adds a kconfig to signal
that the callbacks should be exclusive to each other.
In other words, if one is set, the other should not
be active. Drivers implementing both APIs have been
updated to remove the callbacks from the other API.
Though, this still leaves the option to disable
the kconfig and allows both APIs to have callbacks
if one desires.

Boot level based on parent node (PCI or no PCI device). Some platforms the
PCI bus driver depends on ACPI sub system to retrieve platform information
such as interrupt routing information. But ACPI sub system currently
support only post kernel and hence such platforms the UART driver instance
init should be invoked only post kernel in case parent node is PCI.

The stm32 UART can output a "driver enable" signal on the RTS pin that
allows controlling e.g. external RS-485 drivers.
This can already be configured through the devicetree using the `de-*`
properties, but not through uart_configure(). This commit enables the use
of .flow_ctrl=UART_CFG_FLOW_CTRL_RS485.
This is supported on all devices other than l1, f1, f2, and f4 as found by
this search:

drivers: serial: uart_sam0: fix uart_sam0_irq_update TXC reset bug
uart_sam0_irq_update function resets flags that will cause int. re-entry
existing implementation also clears the TXC flag if it is set
this breaks transmit complete detection
Per the SAMD5x/E5x Datasheet Sect. 34.8.6, writing '1' to the TXC will
clear the flag and disable TX complete interrupts, this should be
preserved through the irq_update for use in the tx_complete check function
The proper fix will cache the TXC value before conditionally clearing the
flag based on that cached value. If you do not condition this on the
cached value a race condition will periodically occur where
the TXC is cleared but never cached.

Recent refactoring of the uart_async_api test (see commit
eb44414af9) revealed an issue
in the uart_nrfx_uart driver that it requested the next RX

All posix arch boards are required to provide the same
tracing/print API.
So, instead of having a different driver for native_posix and the
bsim boards, let's have a common one which uses this API.
This in turn results in the printk strings being printed in
the same underlaying backend as before with individual drivers.
A part from this, the native_posix console driver was a full
backend for the now long gone Zephyr console shell
(named legacy_shell from 527256501f
until it was retired in fd0b7f7767).
The whole input handling in this driver was dead code
(since 140a8d0c8a)

API function:
- `pl011_irq_tx_enable` is expected to enable and trigger TX interrupt.
Due to HW limiation, PL011 won't trigger TX interrupt if some data
wasn't filled to TX FIFO at the beginning. So that `isr_cb` must be
called at first time to enable TX irq.
- `pl011_irq_tx_ready` will return true when FIFO can accept more
data. Here we don't need wait TX FIFO to be empty.
- `pl011_irq_tx_complete` will return true when all data have been
sent from the shift register.

To reduce the interrupt latency of MIWU events, the driver prepares a
dedicated callback function item list for each MIWU group in this PR. We
needn't check the MIWU table and group of the event in ISR. And the
maximum item number of each list is also limited to 8. After applying
this PR, the interrupt latency reduces to ~10us consistently.
