Remove obsolete LargeTexture, it's no longer useful since 3.x

It existed in early Godot releases to allow working around hardware limitations
on max texture sizes (e.g. hardware limits of 1024x1024 pixels).

Nowadays the max texture size supported natively by Godot is 16384x16384, and
even low end mobile hardware should support at least 4096x4096.

The LargeTexture implementation is basically just an array with offsets, sizes
and textures and should be easy to replicate with a custom Texture resource if
needed - solving most of its bugs on the way as the implementation removed here
has various unimplemented or incomplete methods.
