[ELF] Rename BaseCommand to SectionCommand. NFC

BaseCommand was picked when PHDRS/INSERT/etc were not implemented. Rename it to
SectionCommand to match `sectionCommands` and make it clear that the commands
are used in SECTIONS (except a special case for SymbolAssignment).

Also, improve naming of some BaseCommand variables (base -> cmd).
