Use the RTIO work queue to fake the i2c submit calls for drivers which
haven't yet implemented the API. Applications can change the size of
the work queue pool depending on how much traffic they have on the buses.

The I2C API itself now enforces last msg stop, remove duplicate code
from driver.

This change marks each instance of the 'i2c_driver_api' as 'static const'.
The rationale is that 'i2c_driver_api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

This split the repeated START condition to STOP + START conditions.
The old implement may cause undefined behavior for gd32 i2c, like
enter STOP condition accidentally.

Updates the API and types to match updated I2C terminology. Replaces master
with controller and slave with target.
Updates all drivers to match the changed macros, types, and API signatures.

Stop relying on <soc.h> to access HAL APIs. Use generic, per-API headers
instead. Note that <soc.h> has been left as is for now, since ARM MPU
relies on a fragile chain of includes/type definitions.
This change should improve compilation efficiency, as we no longer pull
APIs that are not needed. A similar approach is followed by STM32
drivers.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Add an interrupt driven i2c driver for gd32 i2c peripheral.
The transmit and reception method refer from GD32 SoCs user manual.
Particularly, reception method choose the solution B.
There have some wait for state ready logic in the driver. It cause by
i2c device internal state change slower than i2c driver.
