Add IS_BIT_MASK() macro for determining whether a value is set bits
continuously from the LSB.
This macro is not dependent on bit-width and works in contrast to
BIT_MASK() and BIT64_MASK().
IS_SHIFTED_BIT_MASK() is a version of IS_BIT_MASK() that allows setting
the start bit of continuous bits.

After adopting the `<sys/stat.h>` header from picolibc, there is
a possibility that the following types are not defined.
```cpp
typedef int dev_t;
typedef int ino_t;
typedef unsigned short nlink_t;
typedef unsigned short uid_t;
typedef unsigned short gid_t;
typedef unsigned long blksize_t;
typedef unsigned long blkcnt_t;
```
Of the above missing types, the oonly ones that are used today
in Zephyr are `blksize_t` and `blkcnt_t`.

This may be getting ahead of the curve a bit, but here we adopt
the `<sys/stat.h>` header from picolibc. It is mostly the same

more "inclusive".
Removed the `<_ansi.h>` include.

The remaining types that needed to be harmonized between
Newlib and Zephyr's POSIX definitions are:
* `struct sched_param`
- don't re-define if using minimal libc
* `pthread_attr_t`
- convert to `struct pthread_attr`
- define type if using minimal libc
- assert acceptible object size
* `pthread_mutexattr_t`
- convert to `struct pthread_mutexattr`
- define type if using minimal libc
- assert acceptible object size
* `pthred_condattr_t`

Part of the POSIX Roadmap for LTSv3 is to adopt POSIX-related
headers from Newlib. The strategy to get there is to first make
the existing POSIX subsystem work in the presence of Newlib POSIX
types.
Part of the strategy involved adopting Newlib's `uint32_t`
abstraction for some Zephyr POSIX types.
However, some types are declared as structures. Luckily, the API
only passes those structures around in the form of pointers, and
the API only mutates those structures via global functions. With
that, we are able to alias Newlib POSIX types as Zephyr POSIX
structures.
One of the caveats to doing that without introducing stack
corruption is to ensure that the Zephyr POSIX types are <= their
respective Newlib counterparts.
There was only one Zephyr structure for which that requirement
did not hold: `pthread_attr_t`. We left `pthread_attr_t` as the
Newlib definition, and named the Zephyr variant
`struct pthread_attr`.
On 32-bit machines, both structures were 32-bytes.
```
sizeof(pthread_attr_t): 32 sizeof(struct pthread_attr): 32
```
However, on 64-bit machines, `pthread_attr_t` was 40 bytes, while
`struct pthread_attr` was 48 bytes.
```
sizeof(pthread_attr_t): 40 sizeof(struct pthread_attr): 48
```
That triggered the following assertion.
```
BUILD_ASSERT(sizeof(pthread_attr_t)
>= sizeof(struct pthread_attr));
```
The `stacksize` field was subsequently changed from `size_t` to
`uint32_t`, and that reduced the latter to 40 bytes as well,
solving the last real problem.
```
sizeof(pthread_attr_t): 40 sizeof(struct pthread_attr): 40
```

Some regulators are enabled by default, however, such condition cannot
be captured now by the regulator driver API. Refactor
regulator_common_init_enable to regulator_common_init (enable removed,
as it also sets mode) and add a new argument to specify such condition.
With this change, regulator_disable() and regulator_is_enabled() work as
expected without a first call to regulator_enable().

Some RISC-V SoCs implement a mechanism for hardware supported stacking /
unstacking of registers during ISR / exceptions. What happens is that on
ISR / exception entry part of the context is automatically saved by the
hardware on the stack without software intervention, and the same part
of the context is restored by the hardware usually on mret.
This is currently not yet supported by Zephyr, where the full context
must be saved by software in the full fledged ESF. This patcheset is
trying to address exactly this case.
At least three things are needed to support in a general fashion this
problem: (1) a way to store in software only the part of the ESF not
already stacked by hardware, (2) a way to restore in software only the
part of the context that is not going to be restored by hardware and (3)
a way to define a custom ESF.
Point (3) is important because the full ESF frame is now composed by a
custom part depending on the hardware (that can choose which register to
stack / unstack and the order they are saved onto the stack) and a part
defined in software for the remaining part of the context.
In this patch a new CONFIG_RISCV_SOC_HAS_ISR_STACKING is introduced that
enables the code path supporting the three points by the mean of three
macros that must be implemented by the user in a soc_stacking.h file:
SOC_ISR_SW_STACKING, SOC_ISR_SW_UNSTACKING and SOC_ISR_STACKING_ESF
(refer to the symbol help for more details).
This is an example of soc_isr_stacking.h for an hardware that doesn't do
any hardware stacking / unstacking but everything is managed in
software:

The macro BT_CONN_INTERVAL_TO_MS was used a fair amount
of places, but it often was used with integers. This meant
that sometimes the resulting (integer) value would be
incorrect, as something like 7.5ms interval would not
be properly stored as a integer in millisecond units.
Adding BT_CONN_INTERVAL_TO_US allows users to still use
integers to store the result, but in a more accurate unit.
