Update the Platform Respository for the Juno platform
to include support for generation of the Processor Properties
Topology Table (PPTT) using the Dynamic Tables Framework.

The Platform Repository now also describes the cache and
processor topology in Juno (all revisions).

Changes can be seen at: https://github.com/KrzysztofKoch1/edk2-platforms/tree/392_dynamic_pptt_juno_v2

Notes:
    v2:
    - use ARRAY_SIZE macro from Base.h to compute array size [Leif]
    v1:
    - add support for dynamic generation of PPTT [Krzysztof]
