Fix Plane B scrolling bug

This bug occurred when HSRAM values for Plane B were `>= 0x10000 - config.h40_extra_columns * 4` (e.g., `0xFFD8` when h40_extra_columns = 10) because of a bit carry into the upper 16-bit word of `xscroll`.

[Core/MD] fixed MegaSD edge case occurring when 'play' command is sent while previous track fade out is still in progress

[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).

[libretro] removed genesis_plus_gx_libretro.so from repository (accidentally added in https://github.com/ekeeke/Genesis-Plus-GX/commit/e389f577c9fb3efa542527b5ed1875eb207187f8)

This properly addresses the loading issue in Retroarch with compressed files reported by https://github.com/libretro/Genesis-Plus-GX/pull/249

This reverts commit cc8a6725.
