  [OpenMP] Fix norespect affinity bug for Windows

KMP_AFFINITY=norespect was triggering an error because the underlying
process affinity mask was not updated to include the entire machine.
The Windows documentation states that the thread affinities must be
subsets of the process affinity. This patch also moves the printing
(for KMP_AFFINITY=verbose) of whether the initial mask was respected
out of each topology detection function and to one location where the
initial affinity mask is read.
