This change marks each instance of the 'spi_driver_api' as 'static const'.
The rationale is that 'spi_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.

Add spi_cs_is_gpio(_dt) helpers to check whether SPI CS is controlled by
GPIO or not. This both improves code readability and isolates SPI
internals.

As of today it is not possible to use SPI dt-spec macros in C++,
something known and documented. The main reason is because `cs` property
is initialized using a compound literal, something not supported in C++.
This PR takes another approach, that is to not make `cs` a pointer but a
struct member. This way, we can perform a regular initialization, at the
cost of using extra memory for unused delay/pin/flags if `cs` is not
used.

There have an extral TBE interrupt event though we have cleared the
SPI_CTL1_TBEIE bit. To cover this situation, add a on_going check
before enter exchange function.

This commit updates the GD32 SPI driver to reflect the
`spi_context_complete` and `spi_context_lock` function signature
changes introduced in the commit
4c20403629.

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.
