MLECO-2919: Restructuring to standardise HAL APIs
* LCD module component created (removed from individual
platform packs).
* retarget.c moved out into its own component that wraps
the uart module. It also have the native stub for
GetLine => paved the way for removing data_acq module
from profiles.
* shortened names for components' dir for npu and ta
* remove peripheral_memmap and peripheral_irqs headers
from platform_drivers.h. There should be no need for
these to be included in the top level now. These should
be private headers.
* cmsis_device moved in as a component.
* Pyenv created by set_up_default_resource.py will also
install packages that CMake's source generator needs.
TODO's:
* Remove timer from profiles (MLECO-3096)
