fix(wm): match display name / avoid id volatility

This commit replaces all usages of MONITORINFO with MONITORINFOEX in
order to retrieve a name for each connected display device.

This display device name makes for easier deduping during monitor
reconciliation, so that matching display monitor names can simply have
their hmonitor id updated instead of trying to figure out which id
corresponds to which monitor by looking at the windows currently visible
on each.

fix #267
