Updates to AZ::IO::Streamer configurations

- On Windows the game now has file read sharing enabled for debug and profile builds. On Windows 10 the performance impact is neglectable, so it's been turned on to remove the need for the "cl_streamerDevMode" command line option.
- The drive that handles the virtual file system has been added to the game by default for debug and profile builds. Previously this required using "cl_streamerDevMode" which can now be omitted. A previous update already made it so that the drive would only be added if /Amazon/AzCore/Bootstrap/remote_filesystem was set to 1, but the configuration wasn't updated to reflect this.
- Removed some comments to keep the setreg files clean. The non-specialized versions of the same setreg files still have the comments.
- Removed the "DevMode" configuration (used by cl_streamerDevMode) from the game except for debug and profile. This configuration contained development tools which are not needed for release builds.
