[request] Add BIOS support for Neo Geo Pocket and Pocket Color

Like the title say, Firmware support of both the Neo Geo Pocket Bios and the Neo Geo Pocket Color Bios

• Neo Geo Pocket Bios
• Neo Geo Pocket Color Bios

Noticed. Note that the NGP core used in Bizhawk is not a wonderfully accurate one, so other accuracy fixes might be more useful.

I just updated the NGP core to match upstream, which brought in a bunch of fixes that improve some game compatibility. But the Mednafen docs still say this:

The Neo Geo Pocket (Color) emulation in Mednafen is not very accurate in terms of low-level details; BIOS is HLE'd, CPU instruction timing is totally fubared, and some CPU instructions are likely emulated incorrectly. It's sufficient to play most of the commercially released games fairly well, but if you want to do NGP(C) homebrew development, you're better off at looking at something like MAME.

Lowering the priority again because MAME is a mess and I don't see anyone doing anything else for such a low popularity system.
