refactor: toolcontext: add struct cmd_context_initialized_parts

Add struct cmd_context_initialized_parts to wrap up information
about which cmd context pieces are initialized and add variable
of this struct type into struct cmd_context.

Also, move existing "config_initialized" variable that was directly
part of cmd_context into the new cmd_context.initialized wrapper.

We'll be adding more items into the struct cmd_context_initialized_parts
with subsequent patches...
