[Libretro] Rework "Hide Master System Left Border" option
...
Reworked the option so that now you can hide either 8 pixels on both left and right sides of the screen, or the 8 pixels on the left side only.
Also added a check that makes sure it doesn't cut whenever VDP register $00 bit 5 isn't set, which prevents the option from cutting when it's not necessary (e.g. the title screen of Gangster Town, the half pipe stage of California Games, the Phantasy Star menu screen).

Add experimental overclock option.
...
This reduces all cycle costs by half for the primary CPU. There
is a delay upon loading before overclocking is applied as a
workaround for some games that detect PAL/NTSC systems by counting
cycles in a frame at startup.
