efi_loader: capsule: add back efi_get_public_key_data()

The commit 47a25e81d35c ("Revert "efi_capsule: Move signature from DTB to
.rodata"") failed to revert the removal of efi_get_public_key_data().

Add back this function and move it under lib/efi_loader so that other
platforms can utilize it. It is now declared as a weak function so that
it can be replaced with a platform-specific implementation.

Fixes: 47a25e81d35c ("Revert "efi_capsule: Move signature from DTB to
.rodata"")
