Initial "System Information" page, new font, development coldboot titles, optimized drawing routines

[GerbilSoft]

This is my first PR for recovery_menu, and it has quite a few improvements.

• gfx.c: Optimize drawing routines. Use pointer arithmetic instead of calling gfx_draw_pixel() for each pixel, inline rectangle drawing, and other improvements.
• Use Terminus 8x16 bold on the gamepad and Terminus 12x24 bold. This significantly improves legibility on the TV, since the TV font is no longer nearest-neighbor scaled. The font is also more legible in general because it's 8x16 instead of 8x8. The font is compressed using LZO1X, which required adding a copy of MiniLZO, but the size of MiniLZO plus the compressed font is smaller than the uncompressed font.
• Set Coldboot Title: Print title IDs using hi-lo notation. On systems with Debug keysets (or Factory), allow setting SCT, DEVMENU, or Kiosk Menu. (Fixes #9)
• Added a System Information screen. This currently shows the model number, serial number, keyset, boardType, sataDevice, consoleType, and Wii U Menu version. (Fixes #7)

Screenshots of the new features: (taken with my TV's built-in Capture function, so they're not that great)

Main menu, with the new Terminus font:

Set Coldboot Title showing dev-specific titles, since this is a CAT-I kiosk unit:

System Information: (serial number is visible; I don't particularly care, since it's a kiosk unit without any accounts tied to it)
