mesa: Add support for glGetTexImage on GL_TEXTURE_1D_ARRAY

Browse Source 
Similarly to how we handle this in texstore, we have to remap height
to depth so that we MapTextureImage each image layer individually.

Fixes part of Intel oglconform's int-textures advanced.fbo.rtt

NOTE: This is a candidate for the 8.0 branch.
