Improve UpdateConfig command

[josesimoes]

Description

• Add "Done" field.
• Update declarations of ConfigurationManager_StoreConfigurationBlock to handle new parameter.
• Update code accordingly, namely on ESP32 and STM32 that can only perform enumeration after receiving the last chunk.

Motivation and Context

• Targets that receive configuration block in chunks (because of payload size limitations) were performing the enumeration of the config blocks after receiving each chunk. This is not OK because the enumeration should be done only after the last chunk is received.
  In particular this was causing issues when the first chunk didn't contain a network configuration which causes both ESP32 and STM32 to self-create one of these which is wrong and can have a number of side effects. Ranging from overwriting the data that was just received, start writing it after the initial block, writing on flash memory that was supposed to be erased causing the next write operation to fail).

How Has This Been Tested?

• Debugger WPF test app.
