Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.
In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

The XSHUT pin, used to shutdown the device when it is not
in current use, is optional and some boards (like ArgonKey)
leave it tied to vdd. So, the driver must provide a way to
make this part configurable.

VL53L0X_PerformSingleRangingMeasurement() returns a signed 8-bit
integer, not an unsigned 8-bit integer, making the "< 0" comparison
worthless.

The I2C address of vl53l0x are write in hex, but the VL53L0X_I2C_ADDR
type is int.
Fix this by replace "int" with "hex".

Most of sensor channels defined by Zephyr use the main, unscaled
SI unit. We also have SENSOR_CHAN_ALTITUDE which is defined in
meters. So, it only makes sense to define distance in meters too
The only driver supporting SENSOR_CHAN_DISTANCE as of now is
vl53l0x.c, which was updated accordingly. Also, update doc links
in the driver based on the review comment.

Move to new Kconfig pattern in which we use an if !HAS_DTS_I2C_DEVICE
block for the Kconfig symbols that can now come from DT generation.
This pattern is useful to allow us to define default values for the
generated symbols for build-all testing.

The generic library provided by ST in ext/hal/st/lib/sensor/vl53l0x
needs to be adapted to the platform. In this case, the main
modification is the way to use I2C. This is now using the Zephyr
I2C API.

Add driver for ST vl53l0x time of flight sensor.
This driver can be used in 2 modes :
* proximity sensor :
configure VL53L0X_PROXIMITY_THRESHOLD
will return 1 if target is between sensor and threshold,
else, 0
* distance sensor :
will return the distance in millimeters from sensor to target
This driver use the official STMicroelectronics library for vl53l0x.
