soc: arm: nrf5340: introduce and define SRAM partitions for APP MCU

With this commit we introduce SRAM partitioning for nRF5340
Application MCU. We define fixed partitions for the Secure
and the Non-Secure images, when building with trusted
execution environment enabled (Secure and Non-Secure images).

For (Secure image) builds without trusted execution environment
enabled we now allocate all available Application MCU SRAM into
the single image, except for the SRAM being used as shared memory
with the Network MCU.
