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)
