Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
Automated using:
```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c

Add a bunch of missing "zephyr/" prefixes to #include statements in
various test and test framework files.

As Zephyr currently requires CMake version 3.20.0, update all
occurrences of cmake_minimum_required.

In order to bring consistency in-tree, migrate all tests to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Add a simple ITS driver test allocating 8192 LPIs over 256 DeviceIDS
and 32 EventIDs per DeviceID to exercise the ITS for the MSI/MSI-X
usecase.
The test is set as `build_only: true` and whitelisted to the
fvp_base_revc_2xaemv8a board until the shipped Zephyr QEMU
has the ITS support.
Since `fvp_base_revc_2xaemv8a` needs FIP & BL1 files, test is marked
as `skip: true`.

The ITS needs a number of table, so HEAP must be reserved for runtime
allocation (1MiB is a round and convenient value):
- Redistributor:
* 64K table for all redistributors
* 64k for each redistributors
- ITS:
* 4K collection table aligned on 4K
* 4K x 128 device table aligned on 4K
This makes 11x64K to permit all allocations to success.
Note, will need 64K HEAP_MEM per CPUs added.
This doesn't necessarily include the Interrupt Translation Table,
which are 256bytes aligned tables, for reference a 32 ITEs table
needs 256bytes.
With 14x64K HEAP, up to 116 ITT tables of 32 ITEs can be allocated.
A specific HEAP_MEM_POOL_SIZE as been added to arm64_gicv3_its test
for the fvp_base_revc_2xaemv8a board to satisfy all memory allocation
constraints for 256 ITT tables with 32 ITEs allocations.
