doc: Update WinMR changelog

While not all of these probably should have gone into the main changelog
fragment, there are far to many commits to through and add separate so to at
least have them all listed add them to the main WinMR fragment. Some may have
changelog fragments since before, but doesn't hurt to add them here.

+Added WinMR driver, it supports most headsets and controllers. Controllers can
+be connected both via host-Bluetooth and tunneled with the onboard radio chip.
+By default has 3DoF tracking, it can do 6DoF if used with the Basalt SLAM
+tracking software. Distortion is there but doesn't work perfectly on all
+hardware, best results is on Reverb G2.
