arm: Define elf_backend_extern_protected_data to 0 [PR 18705]

Similar to commit 4fb55bf6a9606eb7b626c30a9f4e71d6c2d4fbb2 for aarch64.

Commit b68a20d6675f1360ea4db50a9835c073675b9889 changed ld to produce
R_ARM_GLOB_DAT but that defeated the purpose of protected visibility
as an optimization.  Restore the previous behavior (which matches
ld.lld) by defining elf_backend_extern_protected_data to 0.
