Support for ARM Compiler C library.
This commit add support for the ARM Compiler C libary in:
- Kconfig
- libc/armstdc
A new Kconfig symbol is added to allow a toolchain to specify if they
support linking with the minimal C library.
Also the CMake variable `TOOLCHAIN_HAS_NEWLIB` is exported to Kconfig
so that CONFIG_NEWLIB_LIBS can only be enabled if the toolchain has
newlib.
The armclang toolchain selects the CMake scatter file generator and
disables support for the LD linker template which is not supported by
armlink.
For the ARM Compiler C library, a corresponding lib/libc/armstc/ folder
with a minimal implementation to work with the ARM Compiler C library
is added.

This commit extends the `Build system integration` section in the Zephyr
modules guide with a description on how a module may append additional
values to Zephyr CMake lists.
This is useful for modules that might need to append values to the
`SYSCALL_INCLUDE_DIRS` list.
This commit is followup to the discussion found in:

Remove Kconfig options
CONFIG_BT_UART_ON_DEV_NAME and CONFIG_BT_MONITOR_ON_DEV_NAME

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Document devicetree compatibles which have changed recently and that

Recent changes to things like / and CPU nodes aren't worth mentioning
since there are no drivers for such things. I'm similarly not going to
document the vexriscv change since it seems likely that users are
getting this compatible via the DTSI file.

Currently, with EATT enabled, when bt_gatt_read is called with multiple
handles first it'll try to use gatt_read_mult_vl, and if it fails
gatt_read_mult will be used to try again. Add option to skip
the gatt_read_mult_vl and use gatt_read_mult right away. This is needed
by tests that expect BT_ATT_OP_READ_MULT_REQ but support variable
lenght, thus don't return BT_ATT_ERR_NOT_SUPPORTED.
Removed fallback from read multiple vl to read multiple on
BT_ATT_ERR_NOT_SUPPORTED error.

The setup() method is trying to find the zephyr repository by name,
but it's not passing allow_paths=False to the west method it uses to
search.
That may lead to unpredictable results depending on what the current
working directory is in the calling environment.
For robustness, disallow paths and make sure we are only searching for
the zephyr project by name.
Add some more comments to explain what is going on and clean up the
empty string handling while we're here.

This guideline address three undefined behaviors listed in the C99
standard. Although Zephyr does not support/implement these functions,
they are part of the C library and could be implemented in the future.
Also this is mandatory rule in MISRA-C and if one day Zephyr decides to
claim compliance with MISRA-C this guideline has to be followed.

Deprecate the xoroshiro128+ PRNG algorithm in favour of xoshiro128++.
xoshiro128++ is a drop-in replacement which is invisible from the user
perspective.
xoroshiro128+ is unsuitable because it is explicitly a floating-point
PRNG, not a general-purpose PRNG. This means that the lower 4 bits of
the output are actually linear, not random (from the designers,
https://prng.di.unimi.it/). This means 1/8th of the generated data is
not random.
Additionally, xoroshiro128+ is not a 32bit algorithm, it operates on
64bit numbers. For the vast majority of Zephyr devices, this makes the
PRNG slower than it needs to be. The replacement (xoshiro128++) is
32bit, with no loss in state space (still 128 bit).
