Revise SystemInfo (#2047)
* Revise SystemInfo Cleans up and adds a bit more info (logical core count and available mem at launch) to logs. - Extract CPU name from CPUID when supported. - Linux: Robust parsing of procfs files - Windows: Prefer native calls to WMI - Remove unnecessary virtual specifiers * Address gdkchan's comments * Address AcK's comments * Address formatting nits
