kib 9b5673f116 amd64: Add md process flags and first P_MD_PTI flag. 
PTI mode for the process pmap on exec is activated iff P_MD_PTI is set.

On exec, the existing vmspace can be reused only if pti mode of the
pmap matches the P_MD_PTI flag of the process.  Add MD
cpu_exec_vmspace_reuse() callback for exec_new_vmspace() which can
vetoed reuse of the existing vmspace.

MFC note: md_flags change struct proc KBI.
