Update i2c_emul.c to support i2c_target_register and i2c_target_unregister
function calls as well as support address forwarding in emulation.
Address forwarding helps us test IPCs in native sim. Instead of having to
emulate 2 separate cores, we can forward read/write requests from one bus
to another bus (effectively creating a loop). This way the same image can
simulate both the controller and the target.

To enable per peripheral queue pool sizing options add some bindings to
the i2c controller to setup sq/cq pool sizing.
Its possible this could go away with a shared application pair of pools.
The shared pool would require some added function pointers though to
deal with the variants as the shared pools would need a lock.

Different nRF52 devices have different maximum TWI DMA transfer size,
and it's easy to hit the limit with i2c displays on nrf52832 (8 bit) and
nrf52810 (10 bit). Currently neither the driver or the hal validate the
limit, leading to random NACK errors when trying to transfer more data.
Add a check on the driver to fail gracefully when going over the limit.

This commit adds option to dump i2c messages of only specified
devices. It makes it easier to debug communication of specific
i2c device instead of logging all i2c communication.
The filter of devices is specifiec in device-tree using the
node with "zephyr,i2c-dump-filter" compatible string.
Example of device-tree node:
i2c-dump-filter {
compatible = "zephyr,i2c-dump-filter";
devices = < &display0 >, < &sensor3 >;
};

The existing i2c sda/slc pinctrl nodes serve as an input and output
for the USIC. This limits the number of pins that can be used for i2c
since the pin must be internally connected to both DOUT0 and DX0 signals
on the USIC (for the sda signal for example).
It is also possible to use separate pins to DOUT0 and DX0, but connect
the pins externally. Add these extra pinctrl nodes and document their
use in infineon,xmc4xxx-i2c.yaml.

In commit 541482ff20 the pinctrl alternate
function mask was increased to also include open-drain setting.
Revert this change because open-drain can already be set via property
drive-open-drain.
The commit also added separate pinctrl nodes for the i2c controller and
target modes. However, the alternate function settings
is the same in both modes, so keep only one and remove the mode
label.

To be consistent with other xmc4xxx drivers.

- Rename clock signal option as it's handled by DX1.
- Remove clock-frequency option as it's already added in
i2c-controller.yaml, and interrupts is already defined as array
in base.yaml.

Sometimes, channel C may write wrong register to the target device.
This issue occurs when FIFO2 is enabled on channel C. The problem
arises because FIFO2 is shared between channel B and channel C.
FIFO2 will be disabled when data access is completed, at which point
FIFO2 is set to the default configuration for channel B.
The byte counter of FIFO2 may be affected by channel B. There is a
chance that channel C may encounter wrong register being written due
to the FIFO2 byte counter wrong write after channel B's write operation.
The current workaround is that channel C cannot use FIFO mode.

This commit aligns TWIM shim to utilize memory-region property.
The memory-region is not required property that enables user
to specify placement of dma buffers in memory region.
It is done by assigning to memory-region property,

When memory-region property is not specified for given
instance, buffer is placed in default RAM region with other data.
