log: Add separate debug option for logging invalid memory accesses

Browse source 
Currently -d guest_errors enables logging of different invalid actions
by the guest such as misusing hardware, accessing missing features or
invalid memory areas. The memory access logging can be quite verbose
which obscures the other messages enabled by this debug switch so
separate it by adding a new -d invalid_mem option to make it possible
to control it independently of other guest error logs.
