cheri: elf: add an RW capability to link_map
For each module keep an RX and an RW root capability. Use the existing
l_map_start for RX (covering all load segments) and add l_rw_start for
RW (covering all writable load segments).
For relocation processing, we also need individual RW ranges to decide
which objects need to be derived from RW and RX capabilities. In
practice most modules have exactly one RW segment and it's unlikely
that any module needs more than four distinct ranges to tightly cover
the RW mappings.
Only added on CHERI targets so always has to be used behind ifdef.
