gdb: update comments throughout reggroups.{c,h} files

Browse Source 
This commit updates the comments in the gdb/reggroups.{c,h} files.
Fill in some missing comments, correct a few comments that were not
clear, and where we had comments duplicated between .c and .h files,
update the .c to reference the .h.
