This changes the database generation to actually extracting individual strings instead of stuffing the whole binary sections into the database. This allows the generation script to be extended to accommodate more output formats. Note that if CONFIG_LOG2_FMT_SECTION is enabled, the format strings are in log_strings_sections, and also have associated debug symbols in DWARF. So there is no need to manually extract them.
