Add codes for DWARF v5 .dwp sections to dwarf2.h. 

(Note: This patch has already been accepted/committed in binutils/GDB.
This will bring the same change into the GCC tree.)

For DWARF v5 Dwarf Package Files (.dwp files), the section identifier encodings
have changed. This patch updates dwarf2.h to contain the new
encodings.  The table below shows the old & new encodings:
