util/sconfig: Re-factor emitting of headers to static.c
This change removes call to add_header from parsing functions and moves it to a local function within main.c. It also adds a new function emit_headers that is responsible for creating the linked list for chip headers and emitting those to static.c BUG=b:80081934 TEST=Verified that static.c for all files compiled using abuild is the same with and without this change.
