[Morello] Add new DWARF defines for capabilities
This patch adds some new definitions required for Morello.
* DWARF base types: DW_ATE_CHERI_signed_intcap and DW_ATE_CHERI_unsigned_intcap.
* DWARF address class: DW_ADDR_capability
* DWARF register numbering
It also adds support for handling DW_ATE_CHERI_signed_intcap and
DW_ATE_CHERI_unsigned_intcap on binutils and GDB.
