sploit: Add ARM/THUMB architecture details
This _should_ be accurate for ARMv7-a at least (including thumb mode).
We might want to later include ARMv8 details, which would primarily
include a 64-bit profile - I just don't have the details at the moment.
A namedtuple is now used as the implementation of type 'Arch', which
allows the definitions to be much more compact and table-like,
aiding readability.
