cogl-pipeline-layer: Use CoglTextureType instead of GL target enum

Browse Source 
Instead of storing the GLenum for the target of the last used texture
for a layer it now stores the CoglTextureType instead. The state name
has been renamed to 'texture type' instead of 'texture target'.
Previously the default pipeline layer would store 0 here to represent
that there is no texture. This has been changed to store
COGL_TEXTURE_TYPE_2D instead which means that all pipeline layers
always have a valid value for the texture type. Any places that were
previously fetching the texture from a layer to determine the target
(for example when generating shaders or when enabling a particular
texture target) now use the texture type instead. This means they will
work even for layers that don't have a texture.

This also changes it so that when binding a fallback texture instead
of always using a 2D texture it will now use the default texture
corresponding to the texture type of the layer. That way when the
generated shader tries to do a texture lookup for that type of texture
it will get a valid texture object. To make this work the patch adds a
default texture for 3D textures to the context and also makes the
default rectangle texture actually be a rectangle texture instead of
using a 2D texture.
