New target methods for memory tagging support
This patch starts adding some of the generic pieces to accomodate memory
tagging.
We have three new target methods:
- supports_memory_tagging: Checks if the target supports memory tagging. This
defaults to false for targets that don't support memory tagging.
- fetch_memtags: Fetches the allocation tags associated with a particular
memory range [address, address + length).
The default is to return 0 without returning any tags. This should only
be called if memory tagging is supported.
- store_memtags: Stores a set of allocation tags for a particular memory
range [address, address + length).
The default is to return 0. This should only
be called if memory tagging is supported.
