Rename `DT_COMPAT_ON_BUS_INTERNAL` to
`DT_HAS_COMPAT_ON_BUS_STATUS_OKAY` to make it a public DT API.
It is helpful for code that handles multiple DT_DRV_COMPAT in one file,
such as in the following cases.
```
#if (DT_HAS_COMPAT_ON_BUS_STATUS_OKAY(some_sensor, i2c) || \
DT_HAS_COMPAT_ON_BUS_STATUS_OKAY(another_sensor, i2c)
...
#endif
#define DT_DRV_COMPAT some_sensor
DT_INST_FOREACH_STATUS_OKAY(DEFINE_SOME_SENSOR)
#undef DT_DRV_COMPAT
#define DT_DRV_COMPAT another_sensor
DT_INST_FOREACH_STATUS_OKAY(DEFINE_ANOTHER_SENSOR)

The 'zephyr,memory-region-mpu' property was addede gqas a
convenient way to create and configure MPU regions using information
coming from DT. It has been used a lot since it was introduced so I
guess we can consider it a Zephyr success story ™ .
Unfortunately it has been proved to be a bit limited and with some
important limitations:
1. It was introduced as a property of the compatible
zephyr,memory-region that is used to create linker regions and
sections from DT data. This means that we can actually create MPU
regions only for DT-defined regions and sections.
2. The naming is unfortunate because it is implying that it is used only
for MPU.
3. It is misplaced being in include/zephyr/linker/devicetree_regions.h
and still it has nothing to do with the linker at all.
4. It is exporting a function called LINKER_DT_REGION_MPU that again has
nothing to do with the linker.
Point (1) is also particularly limiting because it is preventing us to
characterize memory regions that are not generated using the
'zephyr,memory-region' compatible, like generic mmio-sram regions.
While we fix all the issues, we also want to extend a bit the range of
usefulness of this property. We are renaming it 'zephyr,memory-attr' and
it is now carrying information about the type of memory the property is
attached to (cacheable, non-cacheable, IO, eXecutable, etc...). The user
can use this property and the DT API coming with it to act on the memory
node it is accompanied by.
We are still providing the DT_MEMORY_ATTR_APPLY() macro that can be used
to create the MPU regions as before, but we are adding also a
DT_MEMORY_ATTR_FOREACH_NODE() macro that can be used to cycle through
the memory nodes and act on those.

Usage of 64-bit address constants from devicetree without a
UINT64_C wrapping macro results in the following warning and the
cut-off of the address value:
"warning: integer constant is so large that it is unsigned"
This change extends devicetree API adding few wrappers over the
address constant getters which add ULL size suffix to an
address integer literal when the appearance of 64-bit address
values is possible

documenting the guarantee.)

This adds a few bits to the devicetree API tests for multi-bus
nodes where a bus can support multiple protocols. This uses
I3C as basis as I3C controller can support both I2C and I3C on
the same bus, while I2C controller cannot support both. So
this needs to make sure the correct bus macros are generated
if appropriate (and not generated if not needed).

It is frequent to see in Devicetree code constructs like:
```c
#define NAME_AND_COMMA(node_id) DT_NODE_FULL_NAME(node_id),
const char *child_names[] = {
DT_FOREACH_CHILD(DT_NODELABEL(n), NAME_AND_COMMA)
};
```
That is, an auxiliary macro to append a separator character in
DT_FOREACH* macros. Non-DT API, e.g. FOR_EACH(), takes a separator
argument to avoid such intermediate macros.
This patch adds DT_FOREACH_CHILD_SEP (and instance/status okay/vargs
versions of it). They all take an extra argument: a separator. With this
change, the example above can be simplified to:
```c
const char *child_labels[] = {
DT_FOREACH_CHILD(DT_NODELABEL(n), DT_NODE_FULL_NAME, (,))
};
```
Notes:
- Other DT_FOREACH* macros could/should be extended as well

It can be useful to know what a node's index is in its parent's list
of children. This information is now available to C via
gen_defines.py, but no user-facing macros are available to access it.
Add a macro which exposes this information to users via devicetree.h.
Some APIs want to build on devicetree.h by creating some derived
structure for each of a node's children. It can therefore be
convenient to use each child's index in the list of children as an
identifier for the child.
Some concrete and common examples are "gpio-keys" and "gpio-leds",
which allow you to define arbitrary numbers of keys and LEDs as child
nodes of nodes with those compatibles. Derived APIs can use a key or
LED node's index in its list of parents as a way to identify which of
several structures is relevant to a particular controlled key or LED.
These are just examples, though -- the feature added here makes no
assumptions about where it's being used.
