TextureCLUTInShader: Build the CLUT texture from the raw CLUT

Browse Source 
The GLES texture cache keeps 16-bit CLUTs in clutBuf_ converted to its own
component order, and GetClutTexture converted them again, so Fushigi no
Dungeon 4's tiles came out black on OpenGL. The framebuffer depal path
already passed clutBufRaw_.
