Adding support for newer LLVM based Arm Toolchain for
Embedded (ATfE). This is experimental at this stage but
has been tested with versions 19.1.5, 20.0.0 and 20.1.0.
For platforms, these changes have been tested on FPGA
implementations AN552 and AN555 and all variants for FVPs
supported.

Major additions are the CMake toolchain file and linker
scripts, along with required plumbing. CMake presets and
documentation have been updated too. Linker scripts now
have toolchain ID and extensions as suffix instead of just
the extension.

With the associated CMake toolchain file changes, support
for semihosting has also been refreshed, making it possible
to build and run semihosted applications on FVPs easily for
all toolchains. To enable easy boot verification, a simple
HAL test has been added. This needs to be built explicitly
and will produce a small application that boots the target
platform and calls HAL initialisation function.

Addressing couple of issues raised here:

* https://github.com/ARM-software/CMSIS-DSP/issues/242
* #1



CMSIS-DSP was previously using MLEK wrapper to set up the
sources and compilation flags. This was done for legacy
reasons that are no longer relevant. With these changes we
rely completely on the CMSIS-DSP project's CMake config to
avoid unnecessary duplication and maintenance cost.

Compile option passed to Arm(R) Compiler `-ffp-mode=full`
has been dropped as it is no longer required. This has been
replaced with recommended `-ffast-math` option instead.

Minor Jinja2 version bump (Python environment requirement)
is also included.

Minor change to `cmsis_device` target with the `CMSIS_device_header`
definition used instead of `CPU_HEADER_FILE`. This is done to help
with portability as other related repositories use this specific
definition.

Some other changes have been made to address concerns about cyclic
dependency on platform headers from VSI camera interface. Platform
driver target will not add header path to cmsis_device target so the
VSI CMake file doesn't need to know/guess path to platform-drivers
target to get to IRQ definitions it needs.

Fix for recent change to use CMake wrapper for building TensorFlow
Lite Micro - CMSIS-NN kernels were not being included in the build
heavily impacting performance for CPU-only path. This patch has a
minor change to correctly set `CORE_SOFTWARE_ACCELERATOR` CMake
variable to ensure the CMake wrapper actually adds CMSIS-NN to the
build.

Also, with the CMake build flow for CMSIS-NN and TensorFlow Lite
Micro together, the linker scripts have been modified to allow object
file name based memory placement to still work as it was for Makefile
based flow earlier.

For `Sram_Only` memory mode the "weights" RO traffic was previously
wired through the second set of AXI ports and the timing adapter
settings were kept the same as the first set so this traffic also
sees the same bandwidth and lateny envelope. However, it is quite
possible to see slightly better performance if we only use one set
of AXI ports. For Sram_Only memory mode, the Vela compiler schedules
the R/W expecting to use only one set so this change also aligns
with how Vela intends such a model to be deployed on the NPU.

Adding basic Virtual Streaming Interface (VSI) support for HAL camera
interface alongside the default `hal_camera_static_images` library.
Platform drivers for MPS3 and MPS4 targets can enable use of this
library based on a new CMake configuration parameter `FVP_VSI_ENABLED`
By default this is turned OFF.

This will allow all vision-based examples to stream images from camera
connected to a host machine. Although VSI could also be used to read
frames from an input video file on disk (on host), provision for this
has not been added.

Adding a HAL camera and audio interface to allow these as standard
APIs used across use cases. This exercise is primarily to pave the
way for adding Virtual Streaming Interface (VSI) support for Arm
Fixed Virtual Platforms (FVPs) in future work. However, this also
makes the application more portable and easier to add support for
physical (camera or microphone) devices, should we choose to do so.

This patch is big as it cuts across use cases and HAL layers with
platform support. The implementation of baked-in sample images and
audio data is quite old in this repository. To wire things up via
HAL for something which was only application level required touching
quite a few files.

General outline of changes:
--------------------------
 * File generation part has been changed so it generates a self
   contained set of C files in a separate directory that provide
   strongly linked functions that HAL camera or audio interface
   relies on.
 * Two new "components" (camera and audio) under HAL. They have
   weak implementations of functions that should be overridden by
   application sources. The reason for doing it this way is different
   files are generated for different use cases but the there is only
   one target we need under HAL - it is built only once but different
   application sources can override and use this module differently.
 * All the use cases changed to move away from using the generated
   files' functions directly. Instead the static baked-in data is now
   accessed via the HAL provided API's.
 * Tests for all use cases changed for same reason as above.

Byproduct of above changes:
--------------------------
 * Apps don't need to be interactive (user input). The application
   level cannot have knowledge of how many baked in samples we have
   or the filenames. This knowledge only lives below HAL.
 * Tests which were validating inferences by index have been removed.

   parameter: `LCD_TITLE_STRING`.

Additionally, at application level, ImageUtils.hpp now has some more
colours for background and text colours to choose from. These could
potentially be used to drive a "light" or "dark" theme.
