MLECO-2082 Fixes and improvements from OOB
-Fixed noise_reduction CMake bug cause inference to fail when non-default mac_units passed to build script
-Inference complete message added to noise_reduction LCD
-Doc update clarfiy vela.ini config file for compiling to non-default memory modes
-QOL improvement by adding a note on how to make path variables permenant when configuring Arm compilers

For *Ethos-U55* NPU, the system SRAM can also be used to store the neural network model along with the `tensor arena`.
Vela supports optimizing the model for this configuration with its `Sram_Only` memory mode.
Although the Vela settings for this configurations suggests that only AXI0 bus is used, when compiling the model

This means that the neural network model is always placed in the flash region. In this case, timing adapters for the
AXI buses are set the same values to mimic both bandwidth and latency characteristics of a SRAM memory device.
