Make platform feature tag names lowercase

Feature tag names are still case-sensitive, but this makes built-in
feature tags more consistent.

- `Windows` -> `windows`
- `OSX` -> `osx`
- `LinuxBSD` -> `linuxbsd`
- `Android` -> `android`
- `iOS` -> `ios`
- `HTML5` -> `html5`
- `JavaScript` -> `javascript`
- `UWP` -> `uwp`
