bugfixes and improvements for both handy lynx emulator cores

[soundsnow]

The two cores have different bugs and features, @LibretroAdmin better fix them at the same time

These fixes shouldn't be hard, because they are all handy

Handy

bug: Ninja Gaiden III - The Ancient Ship of Doom (USA, Europe)

improvement: Add 180° rotation

improvement: Add database from beetle lynx core for headerless ROMs auto rotation and others

Beetle Lynx

bug: Block Out (USA, Europe)
The Pause button will no longer work. you have already pressed it once and cannot press it again
This games can't be played because it's paused completely

bug: libretro wrong button name and wrong button binding
Opt 1,Option,Opt 2 should be Option 1, Pause, Option 2
Rename the Option to Pause, Rename Opt 1 to Option 1, Rename Opt 2 to Option 2
The button effect of Opt 1 is Option 2, The button effect of Opt 2 is Option 1
Don't change the position of these two buttons, bind them as the correct buttons

improvement: HLE BIOS from handy core

Ninja Gaiden 3 = are you using a verified no-intro rom + real bios? This combo did not crash for me and was able to play quite a bit into the game (intro + act 1).

Most software do not need the database to load correctly, as Handy has backup auto-detection.

Ones that need rotation or eeprom are covered here

Tried Ninja Gaiden III with HLE BIOS but no crashes yet. Need more info please.
