Add a new hw.lcd.density hardware property to AVD configuration files.

This value can be overriden with the already existing -dpi-device <value> option.

The value is mapped to one of 120,160 and 240, then set to the boot-time property
named qemu.sf.lcd_density used by the framework to properly select assets and/or
resize them at runtime.

This means that "emulator -dpi-device 130" will select 120 lcd_density, or
"emulator -dpi-device 220" will select a 240 one.
