feat(masseffectandromeda): add game

[jhi721]

Native HDR fix for Mass Effect: Andromeda (Frostbite 3, D3D11).

Required in-game settings

• HDR: On (HDR10), Framebuffer Format: HALF16 (64 bits)
• Post Process Quality: Medium or higher (grading effects no-op on Low)
• HDR10 Peak Value: max - then set the add-on's Peak Brightness to your display peak

Features

• Vanilla (untouched native HDR) / Vanilla+ (paper white, roll-off, grading, effects)
• Gamma Correction (Off / 2.2 / BT.1886), paper white / peak / UI brightness
• Color grade (exposure, highlights, shadows, contrast, saturation, hue shift, flare),
  bloom / vignette / chromatic aberration, perceptual film grain, RCAS sharpening, AutoHDR videos

Pull request overview

Adds a new RenoDX game module for Mass Effect: Andromeda (Frostbite 3 / D3D11) focused on preserving the game’s native HDR pipeline while providing an optional “Vanilla+” path with paper-white/peak tuning, grading, and post effects.

Changes:

• Introduces the MEA add-on (addon.cpp) that registers custom shader replacements/callbacks and exposes user-configurable HDR + grading/effects settings.
• Adds shared shader injection definitions/utilities plus new shader implementations for tonemap+grade, present tails (1:1 + upscaled), loading/video presents, bicubic upscale sampling, and HDR RCAS sharpening.
• Adds MEA game metadata for deployment/identification.
