[rcore][win32] more style changes and remove old DPI cases

Added some more missing spaces after conditional statements.  Also
made unsupported MSAA_4X an assert instead of an abort and also
removed dpi-aware cases for older OS's.  More changes would be needed
to support those OS versions, namely, removing the dependency
on shcore.
