Wii Classic controller

Fix Wii Classic Controller mapping: positional face buttons, Plus as Start, working left stick, exit combo

• Remap face buttons by physical position instead of label (B->A, A->B, Y->X, X->Y)
  to match the Wiimote/GameCube DC layout
• DC Start now triggers on Classic Plus (Home still works too); Wii U GamePad
  Plus now maps to the real Classic Plus bit instead of aliasing Home
• Fix left analog stick: Classic Controller reports raw 6-bit values (0-63,
  center ~32), not the Nunchuck's 0-255 range, so the old pos - 128 scaling
  left the stick pinned off-center; now scaled via wiiuse calibration data
• Add Minus+Plus exit-to-Homebrew-Channel combo for Classic Controller,
  matching the existing Wiimote combo

2D FRAMEBUFFER fix number 1

Fix 2D framebuffer path: black flash and geometry leak in StartRender

The 2D-after-3D branch re-issued GX_CopyDisp after DoRender had already
copied and cleared the EFB, presenting the clear color as a one-frame
black flash. It now only applies the pending async flip instead of
re-copying.

All bit-24 (2D/RTT-adjacent) exits in StartRender also returned without
reset_vtx_state(), leaving the frame's TA geometry to bleed into the
next 3D render. Added the reset to all four exits (2D-after-3D,
frameskip, post-PresentFramebuffer, and the framebuffer_2d-off return).

Cleaned main menu a bit

MAX_PRESETS from 64 to 4096

There was a limit for presets so I just increase the limit. Can't really for further than 4096. Considering we have ~600 dreamcast games and 2/3 alternative file name, that should fit.
