shader: Rename shader bultin functions
...
Renamed image0TextureSize to imageSrcTextureSize, and removed the
other texture-size functions.
As texture-coordinates are always in image0's texture texels,
calculations with texels are always done with image0's texture texels.
Then, other texture-size functions are useless. To avoid confusion,
let's remove the functions and leave the necessary funciton.

ebiten: Bug fix: Fix the texel calculation
...
In shaders, texCoord is always in texture0's texels. Convert them
at imageNTextureAt functions correctly.
