elfcore: Add a cprm parameter to elf_core_extra_{phdrs,data_size}
commit 19e183b54528f11fafeca60fc6d0821e29ff281e upstream.
A subsequent fix for arm64 will use this parameter to parse the vma
information from the snapshot created by dump_vma_snapshot() rather than
traversing the vma list without the mmap_lock.
Fixes: 6dd8b1a0b6cb ("arm64: mte: Dump the MTE tags in the core file")
