Fix up mediaswcodec security policies.

Add missing include of crash_dump policies for arm/arm64/riscv64
so that updates to crash_dump/debuggerd happen automatically.
Remove the old section from the policy that duplicated the crash_dump
information.

Add an explicit section for AddressSanitizer syscalls to the files
missing them to match all of the other swcodec policy files.

For arm/arm64, the crash_dump policy is too restrictive. In those
cases include a version of the crash_dump policy that doesn't
include the mmap/mprotect rules.
