cmd/link: eliminate a couple of unused DWARF attrs
The linker's DWARF generation occasionally computes and attaches an
attribute X to a type even though the type's abbrev doesn't have the
specified attr. For example, the DW_TAG_subroutine_type abbrev entry
has no type attribute, but a type attr is given to it (wasting
memory). Similarly there are some places where a byte size attr is
added to a DIE whose abbrev lacks that attr. This patch trims away a
few of these not-needed attrs, saving some very tiny amount of memory.
Updates #26186
