many optimizations

- Enable Linuxulator
- Load Intel microcode
- Enable querying CPU information and temperature
- Optimizations for Intel graphics
- Power saving for Intel graphics
- Allow unprivileged users to mount
- Increase ZFS transaction timeout to save battery
- Load fuse filesystems kernel module
- Allow for usb mounting (e.g., kobo reader)
