Omar Sandoval 9da9f6a871 libdrgn: fold struct vmcoreinfo into struct drgn_program
In an upcoming commit, we will parse the AArch64 pointer authentication
code mask either from the VMCOREINFO note or the NT_ARM_PAC_MASK note.
Since it doesn't always come from VMCOREINFO, it doesn't make sense to
put it in struct vmcoreinfo; struct drgn_program makes more sense. So,
make parse_vmcoreinfo() take struct drgn_program instead of struct
vmcoreinfo, rename it to drgn_program_parse_vmcoreinfo(), and replace
struct vmcoreinfo with an anonymous struct in struct drgn_program.
